Apple II mode for X Screensaver
Jamie Zawinski's X11 Screensaver has a nice 'bsod' mode, which shows the Blue Screen of Death and crash graphics from a few other operating systems. I added an Apple II mode, which faithfully emulates the distortions and color reproduction on a late-70s analog television set. Ah, the good old days of 40x24 pages of uppercase text.
