Penrose Tiling

A famous non-repeating tiling pattern, invented (discovered.) by Roger Penrose, a giant in the worlds of mathematics and floor-coverings.

The following logo program produces a penrose tiling. I found this at http://logo.twentygototen.org/E3_yJcQ4.

I haven't looked through it enough to understand it. I can only marvel at its wondrousness.
