Well, this seems an appropriate place to plug the phone/tablet app we made with these puzzles, called Noodles 2.
It's the same puzzle style, with square, triangle and hex shapes, with some extra mechanics - disappearing pieces, infinite grid (it wraps around).
gereleth, great job on the puzzles - I played a few of the bigger hex puzzles and it was real smooth. :)
