A helix from a long time ago, when I was playing around with POVRay quite a bit. The example images in that link show some amazing talent. It’s really neat what you can do with ray tracing when you have time and some real artistic skill. I’m still a bit annoyed about losing a couple of my POVRay source files about 8 years ago since I had no backups of them.

Trivia last night. We were all crammed into a corner (it was the only open table when I got there) and we came in second. Better than 3rd, at least, we got a $25 gift card to the pub for our performance. That means everyone gets about $3 off their dinner next week—which is always useful.
