That is a really wierd effect, but it certainly looks a LOT different than anything else produced in Bryce. I must admit that I love the metallic colors - they give the piece a mesmeric glow that's hard to resist.
Thanks! One of my favorite things to do in Bryce is to put the camera inside a mirrored mesh, a sphere, cone, skull, shark ... etc. , and add a couple light sources with gells. Usually creates some werid stuff.
