You have probably already seen one of these nice POV (Persistence Of Vision) clocks, that quickly move some LEDs in the air to display the time, giving you the impression that the imte is floating in the air...

Today I came across a nice POV gadget: the SpokePOV. By attaching a row of leds to each of the wheels of your bike, you can display some nice pictures and even some simple animations. Unfortunately each wheel can display only one color, but it's still enough to do some pretty good looking displays :

You want one ? Guess what ? Some kits and parts are available here.

Thanks Ladyada for sharing this great concept with us !
