Working on incorporating Rainbow images into various items. Took a rainbow image from a Bing search, enhanced it via Blender rendering, then simply textured into a simple crystal lamp for each shard.
I use the purchased PRISM node from Blender Market which created the attached picture so for submission, i substituted the Blender Glass node.
Feel free to use as you like and if you want to reference me thanks ahead of time.
