POV = Persistence of Vision. I actually designed a basic POV unit in college (back in the day), but it was for a digital design class, so used only discrete logic. These days a small embedded processor would do the trick with more finesse and flexibility....just like the little clocks that are popular these days.
Regardless, this is a POV unit that fits inside the spokes of a bicycle, with a sensor that detects the speed of rotation. The LEDs are turned on accordingly and provide a nice image as you cycle along.
