A DOS screensaver that would convert the current text buffer to EGA graphics equivalent, after which animated ants would crawl out from the edge of the screen and gradually eat the text. The ants were programmed to follow randomly generated paths, but would tend to follow tightly looped paths when they had recently fed, but follow paths with a longer loop when they were "hungry", in order to help them find the last fragments of text left on the screen - a very primitive and early form of Artificial Intelligence.
Regrettable written in the pre-internet age when there was no clear and obvious way to share such precious and beautiful things with millions of users.
