retrofuture diamond dust

The retrofuture is now. Would look good on a Formica® table. Or on a beverage coaster.

The boundaries are space-filling. Every 16x16 pixel block contains one of three boundary elements, and a 3-symbol 2x2 replacement system results in a more dense self-similar pattern. This is a 5th generation pattern, colored by diamond orientation and parity of nesting level.

On a large version, in a special frame of mind (imagine that each diamond is a tilted square), it is possible to visualize the pattern as a 3D projection of three orthogonal planes, with squares of a color all lying on one plane. It's a bit disorienting as there is no definite intersection of the planes and even the orientation of the planes is ambiguous.
