Echochrome 2 looks awesome. In it, you use the PS3 Move controller to shine a light onto a bunch of floating blocks, casting shadows that form platform levels on the wall behind them.
Similarly to the first game, your goal is to guide the ever-walking avatar to the exit, but in this game your little man is a shadow on the wall, walking on the shadows of the blocks you're shining your light onto.
Look, just watch the video and you'll get it. It looks great. It's out "later this year".
