Wasn't there a similar program called Bouncy that is out there already, only
having a huge ball and not a smily face...? You didn't lift this code from
there did you...? =P  Well, I'll take a look at it. Do you have a general idea
what the problem is, like does it start up and then crash somwhere, or does it
not work at all...?
