Today's Game Giveaway of the Day (for PCs only, I'm afraid) is Axisnake, a nice bit of fun in which you control a snake trying to find keys and escape from monsters and avoid biting its own tail. Not exactly a faithful snake simulator - the snake eats mushrooms and apples - but nice 3D graphics and fun for a while. It'll be downloadable for another 10 hours or so, you have to install it before the end of the period.
