I finally got my head around WebGPU/wgpu enough to make my own render graph. Now the bubble universe thing is decomposed into a graph of render passes, and I've got some simple parameter animation going.
In this screencap, I'm varying the particle size and transparency and varying the number of particles in two ways in sync with the universe's revolution. The color map is just doing its own thing; that wasn't planned.

The problem with programming eye candy tools is that it's easy to get distracted into making pretty pictures and stop working on the tool. Anyway, here's an interesting spot I found in the universe of bubble universes. If you look at Yuruyurau's original code, there's a parameter, R = τ/200. In this image, I vary R between 0.49 and 0.51. 🧵 9/N #BubbleUniverse
