My anemone piece needed a little color. Here are a few more renderings and a video of the system running. I’ve also added a few more objects to my particle script including particle generators, attractors, and repellers. A faint circle of somewhat random size around each particle gives a little texture in empty space and pushes back older tubes by overlaying a dark texture.
