The Spirograph

Spirograph Drawings

Back in the 1960s we saw the arrival of 'Sprirograph Art'. The art of 'Spirography' as it was called at the time, was based on making drawings using different coloured biros that you could insert into various holes in plastic gear wheels, one of which was then held in a fixed position, while the pen point was pushed forward to rotate the gear it was inserted into. Complicated epicyclic curves then described the interrelationships of various-sized toothed gear wheels, and by swapping the wheels but keeping the same fixed gear, you could develop very compelling geometric images. 



If you travel along Meanwood Road in Leeds you will pass the premises of Kingfisher (Lubrication) Ltd, a company that has been in business since the 19th century and which is mainly known for its precision made grease nipples. The Fisher family were the owners and in the 1950s their son Denys Fisher decided to go to his local university to study engineering. After leaving The University of Leeds Denys then joined the family firm, but he soon decided to set up his own company, Denys Fisher Engineering. By 1961 his company was supplying NATO with springs and precision components for its 20mm cannon and Denys Fisher had begun rethinking how to use his boyhood Meccano sets. In the early 1960s he developed drawing ideas by fitting pencils into the various holes in Meccano pieces, many of which were gear wheels, and seeing what sorts of shapes could be drawn. 


The types of wheels, connectors and gears in Meccano sets

Fisher began to realise that a combination of geared precision engineering and the geometric logic that lay behind the drawing of forms such as cardioids, could be combined to create drawing tools. As an engineer he was used to using drawing stencils when needing to make complex shapes and in the 1960s these were usually made in transparent plastic. A new fad had been around for a few years called 'nail art' and it relied on the development of geometric forms from straight lines. What this had done was to show the general public how beautiful pure geometric form could be and in a time that had a very positive view of everything scientific, geometry not only seemed beautiful, it seemed to offer a future far removed from the grim days of the second world war. Nail art brought an appreciation of maths and engineering into the living room. Simply by having one of these artworks on the wall, it was believed that children would see how beautiful geometry was and would want to be scientists and engineers when they grew up. You can imagine how a trained engineer like Fisher would have seen the potential of the circle if the straight line could be seen as such a powerful shaper of beautiful forms. 

1950s 'Nail Art'

For instance a cardioid is formed by rolling a circle's path across the circumference of another circle, all the while keeping its radius the same. The cardioid is named after the Greek word for "heart" and I suspect it would have been one of the forms made by straight lines that Fisher looked at. The important fact was that its beauty could be appreciated by people who were not also engineers or scientists and he may well have seen a string art cardioid on someone's wall. However although it looks like a Spirograph image, it isn't. 

How to draw a cardioid

If you look at the image on the lid of a Spirograph box you can see how it works. One large geared wheel in the form of a flat circular band has a wheel moving around its inside, a hypotrochoid and a wheel rotating around its outside, an epitrochoid. 


A Spirograph produces mathematical roulette curves of the type technically known as hypotrochoids and epitrochoids. A hypotrochoid is a roulette traced by a point attached to a circle of radius r rolling around the inside of a fixed circle of radius R.

An epitrochoid is a roulette traced by a point attached to a circle of radius r rolling around the outside of a fixed circle of radius R, where the point is at a distance d from the centre of the exterior circle.

An epitrochoid

The Spirograph as it was called, first went on sale in Schofield's department store in Leeds in 1965. A year later, Fisher licensed Spirograph in the USA and in 1967 Spirograph was chosen as the UK Toy of the Year.

The US advertising blurb stated that 'No artistic talent is needed to create handsome decorations in black and white or colours — ranging from simple figures to fantastically intricate patterns.' 

The blurb went on to state, 'Professionals have actually used the Spirograph to design fabrics for dresses, patterns for plates, and ornaments used in printing. But for most people, it will be enough to enjoy the fun of making the designs that the set produces in fascinating, endless variety.'

So you had a product that covered both the art and design worlds and you didn't need any talent, but it was also, 'Fun for math buffs, too. You needn’t have a bent for math to enjoy the Spirograph — but if you have, it will fascinate you all the more.' This device seemed to straddle both art and science and as it was aimed at children, it could be seen to educate them in both art appreciation and science awareness at the same time. 

The Spirograph toy was in fact a new version of an old idea. Precision machines called rose engines had long been used to engrave ornamental designs for paper money and if you have any, (I realise this is becoming a rarity) you might want to take a close look at it and you will probably find that it still has engraved into its surface the patterned decoration produced by a rose engine lathe, which is technically called a guilloché.

Nothing escapes politics. The UK Government has for a while now been advocating STEM (Science Technology Engineering Maths) as the focus for the school curriculum and people in the arts who are worried about the one sidedness of this approach, have been trying to get the Government to also think of STEAM (Science Technology Engineering Art Maths). The Spirograph and its more recent competitors such as the Hypnograph have therefore had a revival. The blurb for the Hypnograph states this: 'Unlike other drawing machines that have hard to understand ratios, the Hypnograph uses an easily understood set of gears. They are all based on factoring the turntable which has 60 teeth. 60 factors into 2 x 2 x 3 x 5. This lets you easily understand the greatest common factor in the set of gears. A 30 gear has a Greatest Common Factor of 30 with the 60 teeth on the turntable. This means that the 30 gear will produce a drawing with 2 curves (nodes). The instruction book provides a chart so you don’t have to do the math but there is also a good explanation of what’s going on with the gears. A couple teachers have told me that it was the best visual explanation of Greatest Common Factor that they had ever seen.'

Hypnograph drawings

Wild Gears

Wild Gears is slightly bigger than Spirograph and is designed with an adult audience in mind. It takes a high level of dexterity and control to use these gears and a fair amount of setting up. The key issue is that all of these drawing machines stress the interrelationship between art and science and assume that beauty of form is both an aspect of art and is arrived at as a result of following geometric principles. 

Tom Shannon

If we now move on and enter the art world the same ideas persist. Geometric principles now described by the artist users as 'forces of nature' but take away the paint and the mess and what you have is another visualisation of a certain type of geometrical or physical principle. In this case instead of using a Spirograph, if you want to make a beautiful drawing, fill a bag with fine sand or drippy paint, tie it to a long string, cut a small hole in the corner of the bag and set up a pendulum construction. 


Joe Kotas

Joe Kotas

Artists like Tom Shannon and Joe Kotas have linked their more painterly approaches to pendulum type drawing machines and because of the perfection of form which emerges if you use a pendulum drawing machine, they have made 'beautiful' art. Do we have to remind ourselves of the 1960s advertising blurb,  'No artistic talent is needed to create handsome decorations in black and white or colours — ranging from simple figures to fantastically intricate patterns.'? Both Shannon and Kotas would state that the reason their work is so special is that they do have artistic talent. But it is perhaps Damien Hirst that has taken this type of idea on to its logical conclusion. 

A work generated by The Beautiful Paintings by Damien Hirst

It has been hard to escape Damien Hirst's latest venture. He has collaborated with international art services company HENI to present his latest project, 'The Beautiful Paintings,' which blurs the lines between digital and physical art through the use of generative and machine learning algorithms. I quote, 'Based on the British artist’s iconic ‘Spin Paintings’ known for their energetic splashes of colour, ‘The Beautiful Paintings’ allows collectors to access an online dashboard where they can choose their combination of colours, styles, shapes, sizes, and mediums to create unique pieces as physical paintings, NFTs or both.'

Damien Hirst and a Beautiful Painting

Damien was always a smart cookie and he knows a winner when he sees one. I suspect like Denys Fisher realising that if you let a biro follow the logic of a moving point within spinning gears, Damien realised that if you put paint on a spinning flat surface something interesting will happen that follows natural laws. People like to see the result of a process where the final result reveals something about an underlying logic or law of nature, and often refer to that 'like' as 'beautiful'. But it is also no coincidence that all of these forms are based on circular movements. 

Back in 2013, an exhibition in Washington, D.C., claimed that humans have an affinity for curves. The exhibition was based on the work of scientists who had created ten sets of images, each set included 25 shapes, which were all variations on a laser scan of a sculpture by Jean Arp. Upon entering the exhibition, visitors put on a pair of 3D glasses and then, for each image set, noted their “most preferred” and “least preferred” shape. The neuroscientists then reviewed the museum-goers’ responses in conjunction with fMRI scans taken on lab study participants looking at the very same images. The scientists found that visitors liked shapes with gentle curves as opposed to sharp points and the magnetic brain imaging scans of the lab participants backed up the hypothesis. 

So it looks as if we combine geometric logic with soft curves we have 'beauty'. A while ago I looked at the Bezier curve and its attraction for the car industry, again we had a certain type of 'beauty' based on soft curves and an underlying mathematical rightness. There is a sort of satisfaction in seeing a regular form developed, especially one that is complex and still bi-laterally symmetrical or in other ways expressive of geometric order. Could it be that we recognise something of ourselves in these forms? Soft curves could easily be used to define biological entities like ourselves, but also plants and flowing forms such as water. 

For thousands of years artists have produced either geometric patterns or used geometry as an underpinning design principle. 

Islamic decorative pattern 

The harmony of these forms has been associated with the all pervading presence of God in everything and is therefore deeply embedded into Islamic culture. 


Mehandi Mandala designs

The artist Jim Gregory has even produced a Mandala Colouring Book. He states that he values the symmetry involved, and considers the experience of colouring them in, to be a spiritual and meditative one. 

There does seem to be something going on here and the various approaches to what could be seen as very similar end results, suggests that an underlying meme is at work. I'm very interested in ways of thinking or ideas that become popular and therefore belong to popular culture and which also seem to pervade 'high art' or religious cultures. They can tend to be dismissed as kitsch, but the fact that they seem to rise up in so many different contexts, makes them for myself, powerful inter-cultural forms of communication. 

Pakistani Mehendi Design

What is also interesting though is how certain artists and engineers have tried to appropriate something that seems to be universal. 



The spin art toys above are no different to Damien Hirst's spin paintings, except of course his are much bigger, on canvas and stretched onto frames. More importantly he would like us to believe that his ability to pour paint is more attuned to his artistic sensibility, and that his spin paintings are better than the ones made by various children over the years. 

It was Picasso that said "It took me four years to paint like Raphael, but a lifetime to paint like a child." In this case it takes a simple purchase on Amazon to allow a child to paint like Damien Hirst. But these mandala shaped images will always fascinate us, they hold our attention perhaps because the source of all life is spherical and within its contours there are constantly changing and reforging rhythms of energies of unimaginable power and complexity. 

The sun

What was a child's toy, is also perhaps a reminder of deep hidden laws of form that pervade the universe.

More drawing devices

I have looked at drawing devices before but have recently come across or remembered others that might be of interest. In particular this area might be of interest to those of you trying to work with ideas that question the 'authenticity' of the hand drawn mark or want to work in that space between photographic representation and drawing from perception. The constrained ball by Giha Woo is a product with lots of design flaws, however as an idea it is fascinating as it suggests that like a ruler you could use this device to draw straight lines. Thinking about it though, it probably wouldn't help that much, but it would be interesting to see what drawings would look like if you made a series of holders like the one illustrated to 'help' you draw. You could convert toy cars or similar objects with small wheels by taping pens, charcoal sticks, pencils etc. to them and seeing how they effected the types of marks you could make. 

The Constrained Ball designed by Giha Woo

David Hockney has used a camera lucida to draw portraits with. If you look at the examples below you can see how the camera lucida changes the way you look. They are actually very hard to use and you need to be already aware of the main issues that face someone trying to do a measured drawing if you are trying to use one. The main problem is keeping a steady and fixed eye point. You need to work looking through one eye and you also need to keep your head very still. The image you will see is also very faint because you are not working in a dark box, but when you get used to using one, you can use it to plot essential points, such as corners of the mouth in relation to width of nose, and in this way you can get a very good likeness. The concentration needed means that you will probably only use it for essential measuring points, therefore other elements of the drawing will probably be sketched in. Look at how the focus on the faces of Hockney's drawings below are much more intense than on the rest of the figure. He would also have had to ask the sitters to keep very still when using the device and they do feel rather 'stiff' in response to the situation. 
David Hockney: Portrait using a camera lucida

David Hockney

You can see how to use a camera lucida in the drawing below. You 'see' the image on the paper and in effect trace around it. Any small change in the head's position would mean however that any accuracy would disappear. 

Camera Lucidas

You can still buy camera lucidas, see but they are quite expensive, however for those of you interested in that grey area between camera made images and drawings they can be fascinating devices to experiment with. 


Artist's proportional measuring dividers

Proportional measuring dividers are another tool used to help measure relationships and once measured they can be used to transfer the measurements to a drawing that is either proportionally smaller or bigger than the original. There are short videos here and here that show you how to use them. Again using a device like this changes the way you draw. The measuring points themselves become part of the drawing and as you take the measurements the choices made as to where to take these from further affect what the drawing will look like. Typically you might begin to break a face down into areas of measurement like the image below. You don't of course have to measure in this way, and finding unusual or unexpected points to begin to measure from can reveal unexpected and novel relationships. For instance you can use these dividers whilst blindfold, feeling for the form and plotting the relationships on paper by pricking holes in the surface. 


Devices that were built to help artists with complex perspective could be become very complicated. Looking at the drawing below, we have a situation that could be developed as a collaborative performance concept. 

A pair of Perspective Compasses. In: Adams, George: Geometrical and Graphical Essays, Containing a General Description of the Mathematical Instruments Used in Geometry, Civil and Military Surveying, Levelling and Perspective, with many new Practical Problems. London 1803


The image above of a perspective drawing device from 1803 suggests many other possible drawing machine inventions and could become a starting point for any of you wishing to revisit these ideas. Perhaps of most interest though is the fact that the drawings done to illustrate the devices are really good drawings in their own right. 

Finally, I have found a Japanese alternative to the chalk line. To see how it works see

Coda: Drawing with a mechanical plotter March 2023

My old friend Terry has been in Australia and when in Perth came across the work of Robert Andrew. As Terry describes it; "In his work a programmed mechanical plotter was connected by wires and pulleys to various points along the top of two facing walls. Suspended from these points were more pulleys and pieces of burnt wood, ochre and rocks. As the plotter moved (spelling Noongar words) the entire contraption of wood and rocks moved and made marks on the wall - but such tiny movements that you had to stare hard to see them. As your eyes tuned in you could see the whole wall was moving." 

As computer driven motors get more sophisticated in terms of their programming, I suspect more and more work will evolve from that interface between the drawing device, or machine for the  construction of drawings and AI and other computer driven concepts. This work of Robert Andrews is very interesting as it on the one hand still attaches us to the natural world of sticks and bits of rock, whilst at the same time bringing us into the human world of high specification technology. His point I'm sure being that the native aboriginal populations of Australia still exist alongside the new immigrant populations of a post colonial time. The old is always with us, even when we want to forget it.

Drawing as data visualisation.

Noah Gubb

The drawings of Noah Gubb remind me of a another tradition in drawing, one that has been documented in detail by Edward Tufte. This type of drawing is usually seen as being the preserve of graphic designers, but as with all visual languages it can be put to use by anyone. Gubb's drawings are simply visualisations of various moves in chess games, and of course this reflection on the game of chess returns us to the now familiar grid. As Rosalind Krauss stated in her seminal text 'Grids', "modernist practice continues to generate ever more instances of grids."
Data visualisation is becoming important as the Government are making more and more public bodies release the information they have on us. For instance the health service has statistics on ageing, birth, geographical location of illness, percentage of deaths occurring due to cancer, inherited conditions; local authorities are supposed to open their databases on housing, the police force on crime figures, etc. These figures can be visualised and artists can engage directly with them. 
I believe that if drawing is going to respond to what is happening now, open source data is going to be one of those areas that will provide rich material. As always these things are not new, look at this drawing (below) of Napoleon's troop numbers and their erosion during his Moscow campaign. 


Charles Minard's map of Napoleon's loss of troop numbers is a complex representation in two dimensions of six types of data: the number of Napoleon's troops, represented by a thinning line; distance, represented by the scaled map, which also includes place names and main rivers; temperature, represented by the linear graph at the bottom of the image; latitude and longitude; direction of travel, represented by beige for the outward journey and black the return; and location relative to specific dates. It also creates a remarkable 'abstract' image, this time of course the data visualised is much more about a tragic human folly, than a simple chess game. 

Aaron Koblin

Aaron Koblin has used data to make complex drawings based on aircraft flight patterns. Unlike Minard's diagram they include no other information, they simply show us how beautiful the patterns are, and yet these images also allow us to reflect on how interconnected we all are.   
This drawing machine (see video) was created by capturing and illustrating dozens of individuals’ heart rates, showed each person’s “unique physiological response” to their environment.

This animation (see video) is close to the way I suspect artists will be driving data visualisation in the future. As an area to work in it has the underlying rightness of geometry and a Modernist aesthetic and at the same time can be used to make clear statements about the world and the strange nature of the human condition. 

Mark Lombardi was the artist who brought the diagram of connectivity firmly into the art world. In particular, by undertaking long and intensive research into the connections between people, he was able to open out a dialogue in relation to power structures and to visualise who was related to who and who was making decisions in relation to who was holding both corporate and public money. His work crossed both art and politics, the structures of interconnection he revealed were visually beautiful, but they often revealed the dark underbelly of corporate finance. As Shakespeare would put it, there was a canker in the rose.



Mark Lombardi

This is also an area where collaboration could be used to great advantage, someone who can number crunch is needed, as well as a data manager who can explain what data means to the layperson, the artist of course can add vision into the mix. 

You don't have to be an artist to produce beautiful drawings. This sequence of drawings below are diagrams of engineering formulas, their beauty lies in their authority which comes from what I would call the 'rightness' of mathematical conviction.









The implications of this type of art are immense and if any of you are thinking of a way to extend your skill-set and make it one that will make you more employable, this is an area to get into. 

Before approaching this type of work try to read 'The Visual Display of Quantitative Information by Tufte', the library has several copies.
