Chromatograph

Like some kind of Lovecraftian chromatography experiment, the propagating fractal boundary in this piece cycles through a rainbow color palette as the active front progresses endlessly onward. Chromatography is often used in chemistry to learn more about the chemical and structural makeup of a mixture and produces analogous gradations to those shown. As with an actual chromatograph, the larger components are laid down first, followed by finer and finer constituents. Another analogue can be found within the fractal nature of coastlines, where detail only ever increases as finer measurement scales are used.
