I was ging to finsh it and look for repetitions later, :)
...but you can see the repetition in the link you posted. Just look at the colors. They are very repetitive, and you can see that the repeating tiles (blue and purple) are not rotated at all in the repeating pattern. It sortof defeats the purpose of an aperiodic tiling.
Anyway I'm very interested in this as well. If you haven't written a renderer yet by this weekend I'll write one and pastebin it here.
