There is a tutorial on the Hilltop Designs web site for building kaleidoscopes in Bryce. You can also download the scenes which makes it a lot easier. He has a 2 way and 4 way kaleidoscope at the moment. Check out the web site here. http://www.hilltopdesign.com/kaleidoscope/ The other thing you said you found sounds like a multi-reflective arrangement which I have used quite often but is really hard to explain without pictures. You basically make a triangle shape (although it can be any shape) out of planes and make them all highly reflective. Then you position some objects inside the structure and they get reflected off of the walls. You can also make the objects reflective too and they will reflect eachother. Hope this helps a bit.
