MiniPOV - Link.

It seems to me the hard part is the rotating connector that allows you to control that many led's without the wires getting all tangled up. Any suggestions for how to DIY that bit of this thing?

Slip rings come to mind, but I wouldn't want to control the led directly with that. (Too many mechanical problems.)
Use three slip rings (PWR, TX, GND) and use a uC to control the leds.

Link didn't take. This should work.

I would use a "IR link", that is: a LED and a phototransistor. Should be pretty straightforward, wouldn't have to be IR either, although some other color than those used in the PoV of course and the photoresistor should only detect the "data-link-LED" so IR is probably easiest :)

I'd like to see this concept adapted to a ceiling fan, with allowances in the software for different speed and diameter fans. :D Would make great bedtime viewing... even if all it was used for was animated sheep jumping a fence.
