Here's a fun game to play. The object of the game is to move the red block around without getting hit by the blue blocks or touching the black walls. They say if you can go longer than 22 seconds you are phenomenal. I was told that the US AirForce uses this for fighter pilots. They are expected to go for at least 2 minutes. BTW, I made 22 seconds after 5 or 6 tries, so it can't be THAT diffucult. The blue blocks move the same way each time, so a few practice runs help.
