This Christmas, my older sis and her hubby decided to spoil my family by buying us a PS3. I'm so out of it when it comes to modern game systems, but I learned today that you can download games off the internet and straight into the PS3... That is so awesome! So the first game I get is Echochrome. Simply put: it's trippy.
Basically you are dealing with a three dimensional world using Escher type logic. The concept is as simple as a tetris game or pac-man, and everything is white except for the black outline that forms the objects. I don't know how to explain this game any better, so here are some Google pics to show ya what I'm talking about:

The manequin guy is falling through the hole, but he is going to land on the object that is two dimensionally below him.




In conclusion, if you've got a PS3 or you know somebody with a PS3, download Echochrome, especially if you like thinker-type games. Oh, and the background music is beautiful, too.
