Pioneering instructional animators Bruce and Katharine Cornwell

"Bruce and Katharine Cornwell are primarily known for a series of remarkable animated films on the subject of geometry. Created on the Tektronics 4051 Graphics Terminal, they are brilliant short films, tracing geometric shapes to intriguing music, including the memorable 'Bach meets Third Steam Jazz' musical score in 'Congruent Triangles.' Their work, distributed by the defunct International Film Bureau, is now out of distribution."

Pierre Hébert: Around Perception (1968)

"Around Perception is a groundbreaking experiment on computer–based animation, consisting of 11 audiovisual events designed to baffle cognition and unrest comfortable notions of reality. Unlike most of his later films, Hébert chose not to collaborate with top–notch experimental musicians and created the soundtrack himself. In this, he followed a method also used by Norman McLaren: to scratch sound directly onto the film itself. The relation between sound and picture, however, is not as symbiotic as in McLaren's Synchromy: although there are organic reactions between the two domains, one is not a direct translation of the other. This, of course, need not be seen as a weakness. Indeed, with its fast–paced changes of color and geometrical patterns, and the employment of Columbia–like richly crafted electronic tones, Around Perception works as a tremendously hallucinatory exercise in trompe l'oeil (and l'oreille) techniques. Or, as stated by Hébert himself at the beginning of the film, an exercise 'for the mind and against the mind'."

Mathematics is the foundation of activities such as knitting, stitching, measuring and cutting that are crucial to crafting and fabrication

The exhibition "Beauty is the First Test" runs form 27 April – 30 June 2013 at The National Centre for Craft & Design, Navigation Wharf, Carre Street, Sleaford, Lincolnshire NG34, UK.

"The group show explores how mathematical concepts underpin craft techniques, aiming to 'demystify a subject that intimates both adults and children', according to the centre. The exhibition demonstrates how mathematics is the foundation of activities such as knitting, stitching, measuring and cutting that are crucial to crafting and fabrication. Showcasing works in disciplines including textiles and sculpture, the show will feature work from artists including Michael Brennand–Wood, Janice Gunner, Lucy McMullen and Ann Sutton.

Alongside the visual proof that maths can indeed be fun – and pretty – the exhibition also presents case studies of five makers, including Gail Baxter and Margo Selby, exploring how the development of their work was furthered by an understanding and appreciation of mathematics."

Sinclair ZX81: semigraphical / pseudographical characters

"If you press GRAPHICS (shifted 9) then the cursor will come up as : this means graphics mode. If you type in a symbol it will appear in its inverse video form, & this will go on until you press GRAPHICS again or NEWLINE. RUBOUT will have its usual meaning. Be careful not to lose the cursor  amongst all the inverse video characters you've just typed in. ...

Right at the beginning are space & ten patterns of black, white & grey blobs; further on there are eleven more. These are called the graphics symbols & are used for drawing pictures. You can enter these from the keyboard, using graphics mode (except for space, which is an ordinary symbol using the  cursor; the black square is inverse space). You use the 20 keys that have graphics symbols written on them. For instance, suppose you want the symbol , which is on the T key. Press GRAPHICS to get the  cursor, & then press shifted T. From the previous description of the graphics mode, you would expect to get an inverse video symbol; but shifted T is normally <>, a token, & tokens have no inverses: so you get the graphics symbol  instead."
