I have really great (an simple) idea for a nice and little project, it's some kind of first person puzzle game, with simple design.
I'm able to make code part myself too (but I'm new with GS), if u r interested, I'll send u PM with idea of my game.
It'll be noncommercial, I can show u some pictures of it's current state (development is stopped cause of my little knowledge).
EDIT: one screen:
