Finished up the project more quickly than I expected; the hardest part was getting the LED matrices to stick to the back side of the skull's "eyes" (using double-sided adhesive sheeting). The prototype was using an Arduino Duemilanove but I moved the sketch over to an Ardweeny so that everything would fit inside the skull.
These displays are *bright*; I have them dimmed down a bit via the setBrightness() construct but they start to flicker past a certain dimming point.
