So after some setbacks (all I'll say is MCLR) I finally finished a 4x4 RGB matrix I build controlled by a PIC 16F88. This is modeled after a friend's light object. Unfortunately the color mixing is not really great but I am able to control each of the 48 LEDs with 32 levels of brightness, resulting theoretically in roughly 32k colors per pixel. I've applied a cardbox matrix and a piece of paper as the cover to show the different colors.

the 16F84a should work just fine with minor code adjustments (registers are different), but I really recommend that you switch to the 16F88 overall. It is faster, has an internal clock, 16 i/o pins and uses virtually the same code as the 84 - and they are a lot cheaper then the 16F84As here.
Unfortunately, I don't have any schematics for my work, but I successfully build a 6x8 matrix using the 15F88 and some logic ICs. Drop me a line at the 'Contact Me' link and I can email you the details.
