What an awesome pattern! I can't see the fabrics too well, but love the pattern, it's very cool.
I remember when Tetris was first released, pc's were not yet hugely available, and we used to play it at work on the one pc in the office. It's a very addictive game!
I really don't need another project at the moment, but would love to do the same sort of thing one day. Would it be ok to copy the idea and do my own some time?
