Computers have their own aesthetics, which come from their limitations. In this talk, I’ll show you a family of glitch art that is so fundamental to the idea of pixels that it has been independently rediscovered, repeatedly, ever since humans first started asking machines to print drawings on paper. Every researcher who has found these has given them a new name – they’ve been called CIRCLE2 algorithms, dot-matrix holograms, degenerate Voronoi patterns, and others – but I think “pseudofractals” is the most evocative descriptor. I’ll talk a little about the mathematics behind these patterns (the Nyquest limit! Chromogeometries!), and I’ll show how you can experiment with creating your own variants in JavaScript, WebGL, or the language of your choice.
