I was thinking, since graal runs in 256 color mode, couldn't it do color cycling which is seen used in many old games like SimCity2000 or LodeRunner.
I think it would be neat, just specify the beginning index out of 0-255, and the ending index which has equal or higher then the first index, then specify the time delays and possibly the direction the color cycles. It would make for some interesting effects on images when combined with setcoloreffect and setzoomeffect
Could maybe add a command for showimgs too
