This is a simple "sumo wrestling" video game for two players. It is based on the rigid body collisions simulation. The object is to push the other player's object into the wall. There is a counter that keeps track of the number of wall collisions for each object. The player whose object has 10 wall collisions loses.
(If you don't see the simulation try
instructions for enabling Java.)
One player controls the blue object using the S,D,F,E keys to activate thrusters. The other player controls the green object with the J,K,L,I keys or the arrow keys. You can hold down a key to keep the thruster firing. You can fire 2 or more thrusters at once. (If the keys don't work, try clicking near an object - this ensures that key strokes are passed to the simulation). On some browsers you might have to type into one of the numeric controls (like gravity) then click near an object before keystrokes are passed to the game.

You might try playing the game with lower or zero damping (friction) force... it is much more difficult! Perhaps you can get an appreciation of how difficult it is to maneuver the space shuttle in outer space.
For more challenge try playing with very light gravity (0.1 to 0.5).
