Maybe it was you vibrating! Seriously. Try this experiment. Take a fork, spoon, or tongue depressor and clench it firmly in your teeth. Tweak the end while watching a Mac (or any other raster device). Voila! Wierd vibrations. It's the interaction of your small movements, your eyes which can't follow the same, and the raster pattern of your Mac.
