Why do LCD readouts, such as digital clocks, appear to "bounce" when you view them and chew at the same time?

I hope that others have also experienced this phenomenon. I could understand that the force of our jaw is enough to cause our eyes to vibrate somehow, but why is it so pronounced in these circumstances?

Here's the key; only one segment of the display is on at a time. This is because only a fixed amount of power is available to the display, so the number 8 (made up of 7 segments) would otherwise be dimmer than a number 1 (made up of 2).

They cycle through so fast that they appear to be continuous... but when your eyes are moving at a relatively high speed, the segments are in relatively different places. Since they're intense and separate, they appear to jiggle more than the surroundings.

If the display were moving in a straight line very fast, you would see the effect there as well.
