Thanks. Certainly I enjoy doing these, and I've learned a fair bit about coding and computers on the way - that's probably the best way to learn, by having some objective in mind and finding out how to do it and improve. Well, as long as I'm not intending to do this for a living, anyway. I'm well aware of how much I don't know. I'm also on a forum that's all about fractals and fractal imagery, and my stuff is good for what it is, but there are some incredible fractal images out there.
Here's another, which is the same target as the previous image, but zoomed in about 5x, to get the 16-bar spiderleg thnigy at the centre.
