I'm a perfectionist too, but ever since December 2004 the projector has been on loan. I never thought it would be here this long.
That's what I've been thinking about with the RGB display. Right now the 8x8 blocks are $240 in quantities of 120. I am waiting for a quote at the 1000-2000 level.
Even if I decided it was worth it, each display has to be updated close to 70Hz*256 shades = about 18kHz. This requires a microcontroller for small blocks of the display like you said. Things start to get expensive!
I would probably settle for a monochrome display. I would REALLY like to build one with the 5x7s, but they seem to cost too much. An 80x20 serial terminal made out of LEDs the size of a 50" TV would be cool.
My current display is the size of a couch, as you can see!
I will try to sell a kit when I am done. The display out of individual LEDs with ALL the PCBs (drivers and LED panels) as well as all the driver chips will be about $1200. Think anyone would bite?
