[Coco] Ideas for a Graphics Project, part 2

[Robert Emery]

Excellent info, thanks Robert. Are there any similar programs for the CoCo3?
Seems like they all rely on palette cycling, but it should be possible to set
up a few graphic pages on a 512K machine and flip through them, possibly
cycling the palette at the same time for some advanced looking animation.
