micro POV display
Overview
mPOV is a project to make small LED persistence of vision displays. The idea behind this is that your retina does some integration of photons over time, so if a one dimensional display is swept across your field of vision, a two dimensional image can end up in your brain for a fleeting instant.

You have probably seen these displays around; clocks, kids toys, etc. For some reason I didn't really get turned on to how cool they are until I saw Frostbyte's famous and mind blowing LED towers, which he was nice enough to bring to several of the parties at 324.

Anyway, if I think something is neat I pretty much always get around to the idea of glueing it to my shaved head. So I wanted to make a POV system that used surface mount LEDs packed in as closely as possible.

Rev x01 has the controller and the LED modules built as seperate boards, so that N LED boards can be chained up to a single controller to form different sized displays. The controller is built around an MSP430 from TI, and the LED modules use a CMOS shift register and 0805 size LEDs from digikey.
