A simple Experiment This is a Sphere IFS inside a RoomClr formula, used the Pinch/Punch adjustment to make the RoomClr Round, Really interesting effect. Transparency and Reflects looked very promising but needed a BG for more interesting Reflects and Color, tried several and settled for an older MB3D titled "Rising" I liked the way it fit and the wild way the Reflects/Refracts worked out, notice the reflects on the center sphere is 180 out from the other like on a Concaved surface, more experimenting to come but I really have been taken over by the Apophysis Bug lately.
What you find a simple Experiment, is in real a great fractal, with some great reflections in it and some fine details, so not a simple one ,but a great fractal by its simplicity
Snot much, just a simple one that worked well with the BG
Well done
