Smoking clover
According to the Jargon File, smoking clover is a computer display hack,[1] originally created by Bill Gosper. Several converging lines are drawn on a color monitor in such a way that every pixel struck has its color incremented—altered to the next hue up or down. The color map is then repeatedly rotated.

The result of this is a rainbow-hued, shimmering four-leaf clover. The program has been described as "psychedelic", and Gosper joked about keeping it a secret from the Food and Drug Administration (FDA) due to its "hallucinogenic properties".
Source code for Linux to reproduce the effect is available on the web.[2]

gollark: "I don't want to only breed on certain days! It's too haaaaaard to check!"
gollark: If people had to *check the day* to breed stuff of a certain colour, it would be *horrifying*.
gollark: Imagine if they were the wrong colour! It would spell disaster for all dragonobreeders.
gollark: Because it's clearly necessary that their groups of pixels look *perfect*.
