When you start it up, little ants crawl all over your screen diagonally, and when they hit the edge, they bounce, pong-like, off in another direction.
Every place they have traversed, the screen goes blank. In about a minute, the screen is blank except for these cool ants crawling around.
One difficulty, though, is that the program was written to move at a speed determined by the clock, and the clock speed at the time was 4.77 mHz. This was 1981, after all.
Today, that program clears the screen in about ten milliseconds and leave some ants traveling at BUGatti speeds (feature=fvst) all over the screen, too fast to even know they are ants.
Oh, yeah -- it also only clears off the DOS screen, as that was the OS at the time. Sometimes, as time marches on, the old stuff just doesn't work any more. Sorry.
A good answer is easier with a clear question giving the make and model of everything. "The biggest problem in communication is the illusion that it has taken place." -- G. “Bernie” Shaw
