I have spent a long time recreating a system that used to be trivial. Back in the early days of computers and arcade machines cycling colors was a novel effect. Even on the Atari 2600, a computer that couldn’t even draw an entire frame to the screen and instead had to parcel it out to individual crt scanlines, programmer figured out ways to cycle though a palette of colors. On some games the most animation you were likely to see was color cycling.
