The disk is filled by distorted pixels that show the evolutions of an elementary cellular automaton starting from three shifted versions of a common initial condition. These three evolutions are represented by red, green, and blue color channels, giving up to eight different colors. Up to six copies of the resulting pixel arrangements fill the disk.

The coordinates of pixel corners are translated into polar coordinates and then squeezed into sectors by dividing their angular coordinates by . The exponent transforms the distance coordinates as .
