Sorry about the "ct" line. I forgot that I had a plugin running in 
the background. "ct" stands for my "clearText" command.

I'm happy and surprised this works for you. I have modified it so 
that it works for polygons of arbitrary number of sides and re-posted 
it at

under the title: Colliding polygonsRevised.rev

Let me know if  this  works  for you.

You can speed up or slow the motion of the polygon by changing the 
values of vx and vy.
