This is a recent piece, inspired by the previous Janus #51.

I liked the previous two, but I was disappointed with the variations I made. So I tried progressively more extreme experiments. The intermediate steps are not worth show, but they led to this. It looks like something nasty seen under a microscope.

The next (saved) variant embraces the floating sets of concentric circles.

Larger components, with transparent glass appearance.

That was fun, two more.

Fewer nested circles is each feature. Old 33 1/3 records?
