Take a look at Figure 1. This figure shows a fractal called the Dragon Curve.\par\bigskip

This curve is a fractal, a term first used by Benoit Mandelbrot. You can
find a picture of him in Figure 2a. Perhaps the most famous fractal is the
Mandelbrot set. Take a look at Figure 2b. A fractal curve is a curve that shows
details on every length scale. A simple square which is not a fractal, shows no
new feature as soon as you look at it, at length scales smaller than its side.

Back to the dragon curve, it can be constructed using the subsequent steps shown in Figure 3. The complete dragon curve is made with infinite steps.
