Ahhhhhh, fantastic!
Can't wait for the source to try it out!
A friend of mine sent me a link a few days ago to this:
http://johanneskopf.de/publications/blue_noise/
Similar idea, based on Wang Tiles (they also do recursive Wang Tiles, which is
even cleverer).
So that's twice in about 4 days I've had my ind blown with seamless tiling!
Cheers,
Edouard.
