One of the neatest-looking PlayStation 3 downloadable games at Sony's booth was Gomibako, which means "trash can."
It's basically Tetris played with trash. You have to load up a trash can with thrown-away crap, one at a time. You're attempting to stack them up such that you don't leave any empty space, and can thus fit a lot more inside. But you can also smash items down into the can, breaking them or breaking the things they land on.
