Swirly things

I had another go at glass and caustics. In my mind I imaged that Blender Cycles can do a glass prism effect without any special workarounds, with the current version of 2.8. Wrong. On the upside, I walked away with some fun renders.

Later I had another go, with simple prim shapes and more colour components. It still looks like a mixed bag as far as real-ish-ness. The big workaround was mixing six glass materials, each with a different colour and refractive index, into one.
