DIY POV Blue LED Display!

Take a moment and watch these awesome displays of the DIY POV blue LED display that will animate a dog. (or horse)  Awesome huh?

Improvements are:
The rotation speed is 25/s instead of 7/s like in the earlier version, thanks to a cooling fan motor, which can give about 10W power and enough torque at 1800rpm. Also the power supplying is changed for the rotating part. It gets negative through the axe, positive through a sliding contact. The rotation speed is monitored, so the image does not collapse when it decreeses.
