Arduino shield for Arduino. No, really.

“Core2duino is — seriously now, no joke — an Arduino shield containing a second ATmega microcontroller and full complement of I/O pins. The two chips in this Young Frankenstein-esque assemblage coordinate over the I2C bus, providing, at least in theory, more processing power, more I/O, and perhaps a degree of fault tolerance. In reality, we’re pretty skeptical, but do have to give them props for a great Instructable, detailing the whole process start to finish with Eagle CAD files, board etching and drilling, and advice on where to score free Cosmopolitan magazines (it helps “if you know any women,” we’re told).”
