RockPaperScissors: a random number of each are randomly         
placed on the screen. They randomly walk around the
screen and is they collide, with one of a different
kind, the looser disappears and the winning type gets
a point. Rock blunts scissors, scissors cut paper and
paper covers rock. This could be played with: if they
all start with the same number for several games do
they all win the same amount of times. If different
numbers for each object does that object with the
greater always win. Is its dependent on which object
it is that has the greater number. If it appears not
to be the case is there a number by which the difference
is such that the one with the greater number always wins.
