Named after his creator Benoît Mandelbrot, the Mandelbrot Set lays on the complex plan and is prone to psychedelic colors.

It is probably the most famous emblem of fractal geometry, defined by a simple "complex" equation. The algorithm is simple: for each point, check if it falls within the set—

• if it does, color it according to a range.
• if it leaps into infinity, give it a spot color (such as black).

Because of its simplicity, this was my first Processing sketch back in 2002. A few years later, it showed up in MoMA's Design and the Elastic Mind book and website.
