This was a technology often used in 8-bit video games of the era, to achieve interesting visual effects by cycling (shifting) the color palette. Back then video cards could only render 256 colors at a time, so a palette of selected colors was used. But the programmer could change this palette at will, and all the onscreen colors would instantly change to match. It was fast, and took virtually no memory. Thus began the era of color cycling. Most games used the technique to animate water, fire or other environmental effects.

Joseph Huckaby wrote the code using HTML5 to animate those illustration to animate part of the environment in it. Stunning!
