There is this guy from Lion Studios (Black n White etc...) that is making this cool innovative game. It's not a commercial one I think so it's prolly gonna be free. It's a fighter and you control the fighters as ragdolls, meaning you pull their arms and bodies with the mouse to make them move/attack.
There are some movies at the site showing it off. It's a very innovative design, hope it's released soon (says "coming this summer" :/ ).
