Here's a fun, maddening challenge.  Basically, use your arrow keys to make the grey circle touch the grey box.  Just don't touch any of the blue balls, or let them touch you, while you are at it.

If you live in a duplex or apartment, don't play this at night as the sound of your screaming may cause your neighbors to rush in and administer first aid and the false alarm may not be covered by your health plan.

Note! - to activate the game, click on the grey circle and then use your keyboard's arrow keys.
