Stefan,

Thanks for the feedback.  I'm using the Animation and Rendering Plugin in
Moray (my fault, if I wasn't clear on that point) and was wondering if
there was away to do it from within Moray. I can embed Povray code-snippets
to 'stobe' the light on and off in the Moray file but I don't know if there
is a way in Moray to pass Povray the current frame info.  I've been coding
for years so that's not the problem. Just figuring to figure out the
mechanics of it all.

Thanks,
Dave...
