Addictive Puzzles

I've always been a sucker for puzzle games -- the kind of person who feels compelled to play Myst or 3 in Three for 48 hours straight because I can't bear leaving the game before it's solved. So I've spent far, far too much time this evening working through Fantastic Contraption. The premise is simple: build a device to carry an object across the screen. In a lot of cases, it's much trickier than it sounds.
