I finally made some acceptably strange columns in Rhino, and the archways are also Rhino-based. A couple of cube primitives when arranging in Bryce, and then some replication and tweaking of space and lights produced this result. 10 lights set to Squared falloff, 10 archway-column sets, and a mirror box to control the "Infinity" of it all. You determine how deep the reflections go with the "Ray Depth" and "TIR" settings. Any ideas on a centerpiece? A fountain? A statue? Shoudl i replace the simple light-globe-inside-glass setups with something more complex?
