there is a kit to make the wheels of your bike into a POV display! Not quite what you meant but still related.

This display really gets to the heart of the Maker Spirit. Combining a power drill and LEDs to create a spherical 'sign'. Wow! Now all they need is the bike powered version (or a steam engine for the steam punk makers out there).

that is exactly why it appears to be a spiral. Interestingly you could probably tell the quality of the camera by how extreme the angle is. the more extreme, the slower the sensor is filling from top to bottom. Obvioulsly this would most likely only be applicable to small device cameras like cell phones. I filmed this with the newest ipad.

Max was thinking about doing something like this with projectors some time ago.  I thought about how to do one with LEDs but didn't think of the POV idea - apart from anything else it hugely reduces the number of LEDs.  Very clever.

Interesting that in the video the LED bars appear as spirals rather than lines - I presume due to the scanning of the Video Camera rather than the timing of the LED illuminations?

Yeah, I really wish I could find a good picture of it running in the evening. It truly looked like a 4 foot tall hovering globe of light.
