# Chapter 8. Fractals

To my mind, there is something very “seventies” about fractal art. Even before James Gleick’s hugely popular book *Chaos: Making a New Science* (1987), which popularized the mathematics of chaos theory, fractal imagery, in particular the Mandelbrot set, was overly familiar from the kind of posters you might expect to see on the walls of hippie math grads.

We’ll never know why the renderers of early fractal art favored such lurid, psychedelic colors, but I assume it had a lot to do with the overconsumption of LSD. Anyway, I want this preconception of fractal art flushed from your mind as we explore self-similarity in this chapter. Fractal art can also be subtle and beautiful (see figures 8.1 and 8.2).
