I think it was Schizoslayer who pointed me at this, but I only had a chance to play it now. It's Fractal, and it's really quite neat puzzler from the makers of Auditorium. The idea is simply you have a limited number of new hexes to push into a grid, which displaces all the other ones. Form larger hexes formed of smaller ones to score points. Elegant and looks great. There's a web-demo for you to play, but the full version will cost you fifteen dollars. GO FOOTAGE!
