8×8 RGB LED Matrix

Here’s a relevant blog entry about it.
For flashing the bootloader I recommend the very affordable USBtinyISP by adafruit. Just program and upload as usual with the Arduino IDE and a USB/TTL converter like this or that. If you have trouble to upload code with the Arduino IDE, maybe auto-reset doesn’t work. There’s a Perl script that enables auto-reset with FTDI USB/serial adapter cables. There’s also the option to upload code by manually resetting the board as described here.
