0xDE's recent toot on cavatappi-like surfaces reminded me of a helical surface I devised a few years ago that had ridges on it. I thought it might be a good way to test the new surface-styling features of the recently released Mathematica 12.3...

I had the thought that visualizing the Padua points (https://en.wikipedia.org/wiki/Padua_points) in the complex plane would lead to nice-looking domain coloring plots. I was not disappointed.

Since @11011110 recently boosted that Lloyd toot I made a while back, I should also state that Lloyd's algorithm also looks mesmerizing when done on a sphere.

Someone wanted "a hole in a hole in a hole", so I thought I'd do something in Mathematica. (log-sum-exp (https://en.wikipedia.org/wiki/LogSumExp) is pretty handy for making "chimeric" surfaces.)

It took me longer than I'd like to figure out how to (cleanly) roll a hyperbola on a straight line, but it worked out. I should try writing up the math behind this later...

I was able to find my old code for plotting the Wente torus (https://en.wikipedia.org/wiki/Wente_torus) in Mathematica again, after losing it in a disk failure. It's really nice to see it again.
