/* Gilad Lotan - 
   Etch & Sketch-"ish" Networked game for two players. 
   Data from potentiometers is stored in a text file on the itp server. It is parsed and
   translated into the visuals of the game. Each colored square must try to get as many 
   points as possible by touching the same colored ball. If the other colored ball touches, 
   then points are deducted.
