JelloCar
Walaber’s JelloCar is an experimental XNA game project which uses his soft body physics library. The game involves driving a car that can change shape with the press of a key, an action which will be repeated quite frequently before the end of each stage is reached.
Press the space key to change the shape of your vehicle, and use the arrow keys to move the car around. Tap the escape key at any time to leave a game in progress or to quit the program directly. [source: Fun-Motion]
