Michu built a LED matrix panel that is controlled by his PixelController software we blogged about. The panel consists of 64 individual RGB modules. The modules have three RGB LEDs on them controlled with a LPD6803 serial shift register LED driver. The color range is 15bit deep, or 5bit per basic color.
By connecting them in strings you can control any individual LED by sending serial data in sequence they are connected on the panel. Or by using his software and a Arduino as USB to serial link.
The panel is built from matted white acrylic making for a very impressive look.
