Indie hit Crayon Physics Deluxe turns 1 this month, and developer Petri Purho is offering it at a name-your-price sale similar to what World of Goo ran back in October.

So, once again, if you feel like being a heartless bastard and paying just one cent for this PC game, that's your prerogative. If you support indie games development, it's a chance to put your money where your mouth is.

The sale is good through Jan. 15 (Friday.)
