There's a nice site on Penrose tiling here ==> [link]
He has a program to create Penrose Tiles, and the source can be downloaded as well. I used his program for some of my older images.
==i might try smoothing the segments as well... Uh, not sure what you mean by that.
Well, its a pun allright, but its a pun on phi and five. Phi being the magic number called the Golden Section, or the Divine Proportion. Its used in Penrose tiling too. phi = (sqrt(5)+1)/2 And five, because of the 5 sided symmetry.
