Knowing that wombats' dump is little stackable cubes was one of the fun facts I learned at school (it was either a rhetorical proof for or against the existence of God; I forget which). This knowledge comes in handy for understanding the game Hardhat Wombat, coming from George Fan (of Plants Vs. Zombies fame), with Andy Hull (of programmer on Spelunky fame). Out later this year, it's a combination puzzle-platformer and conscruction game in which you play a wombat, wearing a hard hat, who constructs increasingly complex things out of his own feces. That is no way to make a skyscraper, wombat.
