heh.  Stand ten feet from your monitor, and snort your nose.  Try to
make a sound like a pig.  Does whacky things to what you see on the
screen, probably because of some effect of the vibration frequency
acting on the retina through your face bones interfering with the
frequency of the screen.  Anyway, it makes it look just like a home
video of a computer screen:  you see the frames move up the screen.
