Neat animation. Did you use two trace statements to get the beam to 
bounce off the mirrors and stop at the more diffuse objects?

I've got a couple suggestions, since the beam is a little hard to see:
  -dim the lights in the room
  -give the cylinders an emitting media with a cylindrical density. The 
density pattern can be rotated using the Reorient_Trans macro, I think.

Now if you're a real glutton for punishment, you can introduce convex 
mirrors and substitute some of the cylinders for cones :)
