you asked how Chromeworld Blue was made. It's pretty easy with Bryce. I put instructions on the comments for that image. But in short you pull a large sphere, put a mirror surface on it (all very easy in Bryce) then you build a simple construction in the middle of the sphere using native primitive objects which you also put a mirror surface on. Then you place some colored lights around, put the camera INSIDE the sphere and move it around a bit to get the shot that you want. Sorry I took so long to get back to you, but I missed your comment.
tnx for the comment... bout the eyes of the cat... we were surprise too. when i took the picture. the cat just posed then the eyes came out so good already... natural photography... no touch up at all... thanks for the comment!
