Hi, I am commenting on "Have you made any progress recently?". No what I am using is one (in principle infinite) string of distances. Now with the program anyone can modify the offset, layers and colors and transparency. With the offset one changes the whole pattern of pentagons. What remains is the rotational symmetry. The latest version has a very good user interface to change the colors and transparency of the layers. And if you are a bit lazy, just press "Q" and it will generate random offsets, colors and transparency, and it will store them too.
