I love this RGB POV in a tube created by rucalgary.
There are 64 RGB LEDs spinning around on an aluminum frame, spun by a motor picked up at Princess Auto for $20.
I control everything via an ATMEGA1284p microcontroller, as it was one of the only micros that had the memory space I needed for images.
I hope to get some more color out of the system by PWMing the color output, but we will have to see that later. Right now I am displaying images just by changing the source code, but I hope to get wireless updates working over Zigbee or Bluetooth.
You can download the code and Eagle files if you want to learn more. [via EmbProj]

Princess Auto FTW!
That is awesome. Fix the vibration, get some animation going and I could see that being a real product with a lot of potential.
Very nice! Add just enough weight to the other side to balance the display. You could remove the display, weigh it, weigh the bar on the other side, and subtract to see how much is needed.
Viewers should know that the moving dark stripe in the video is not visible in real life. It is just on video.
