Thanks. I re-rendering to remove the laser shadow. The laser is also stronger and 
the resolution slightly higher (still mpg though). I'll post when finished.

Sweet deal!  How about with radiosity and a high ambient on those cylinders?
A setup like this with a story/concept behind it would have made a great
entry in the overly complicated machines IRTC round.  Looking forward to the
updated version.

POV-Physics 6.5.9.6 - Fake laser beams will cast shadows unless created with 
no_shadow sources... doh. Thanks to everyone who pointed that out.

Here is an update, no shadows, slightly higher resolution.

I saved it.  :o)  It's better, but still doesn't really look like 'light'..
But how did you calculate the position of the mirrors?

No.  Light will not block the passage of light.

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 :)

I know :-( This was meant to be a quick experiment, but maybe I'll try to improve 
the laser beam.

Most were easy (90 degree deflections). The others used simple trig.
