This fun new toy will look familiar to anyone who remembers playing with a pre-digital version. You get 8 slider variables to play with, and 3 colors (2 foreground, 1 background), for an amazing (though probably technically not infinite) variety of designs. Mesmerizing, maybe, or inspiring, or distracting, or intriguiging, or “just” entertaining. What could you design with it?
(From subblue Mathematical and Generative Graphics, which calls these “Guilloché Patterns” and suggests you use them to design your own banknotes. Requires Flash plug-in.)
