The Dragon Curve/Jurassic Park Fractal
A dragon curve is any member of a family of self-similar fractal curves, which can be approximated by recursive methods such as Lindenmayer systems.
Construction: Starting from a base segment, replace each segment by 2 segments with a right angle and with a rotation of 45° alternatively to the right and to the left. Here’s a visual:
It can also be created by folding paper! There’s a great Numberphile video that explains the dragon curve construction.
So, why is it called the “Jurassic Park Fractal”? In the Jurassic Park book, iterations of the dragon curve were used with the following quote by Dr. Ian Malcom: ”At the earliest drawings of the fractal curve, few clues to the underlying mathematical structure will be seen”. The dragon curve was used to hint at the themes of chaos and unpredictability in Jurassic Park.
