No sound today. I was thinking of making something that might look like a Shepard’s Tone and I came up with this simple idea of a complex polygon that expands outwards into the viewer. I got it going and then I thought it would be cool for it to be endless. I will have to think how I can do that practically. I have a feeling it will borrow some waterfall code and test to see if vertices are out of visual range and then put them back into the pile. I think I will need to sleep on that one.
