I’ve been playing with ceiling fans and POV a little too, partly to see what would happen, and partly to mess with motion blur and POV rendering in Pixel Teleporter.
My experience is that yeah, you can make it work but… a ceiling fan operating at normal speed is too slow for a good visual, and if you crank it to max speed, it looks slightly better but every little blade imbalance or loose part or swinging switch chain starts shaking the fan and rattling around. It’s not something you can really leave running for very long.
FWIW, Here’s a test render of a strip on a single blade running at 480 rpm, which is maybe 100 rpm faster than my ceiling fan can actually go. I’ve got some work still to do on motion blur, but you can see what it’s supposed to do.
