smoking clover
[ITS] A display hack originally due to Bill Gosper. Many convergent lines are
drawn on a colour monitor in AOS mode (so that every pixel struck has its colour
incremented). The lines all have one endpoint in the middle of the screen; the
other endpoints are spaced one pixel apart around the perimeter of a large
square. The colour map is then repeatedly rotated. This results in a striking,
rainbow-hued, shimmering four-leaf clover. Gosper joked about keeping it hidden
from the FDA (the US's Food and Drug Administration) lest its hallucinogenic
properties cause it to be banned.
