Harter-Heighway Dragon Curve
- This image is an artistic rendering of the Harter-Heighway Curve (also called the Dragon Curve), which is a fractal. It is often referred to as the Jurassic Park Curve because it garnered popularity after being drawn and alluded to in the novel Jurassic Park by Michael Crichton (1990).
Then at each iteration,
- Each line is replaced with two line segments at an angle of 90 degrees (other angles can be used to make fractals that look slightly different).
- Each line is rotated alternatively to the left or to the right of the line it is replacing.
The Harter-Heighway Dragon is created by iteration of the curve process described above, and is thus a type of fractal known as iterated function systems. This process can be repeated infinitely, and the perimeter or length of the dragon is in fact infinite. However, if you look to the image at the right, a 15th iteration of the Harter-Heighway Dragon is already enough to create an impressive fractal.
An interesting property of this curve is that although the corners of the fractal seem to touch at various points, the curve never actually crosses over itself. Also, the curve exhibits self-similarity when iterated infinitely because as you look closer and closer at the curve, the curve continues to look like the larger curve.

Future Directions for this Page
An animation of the fractal being drawn gradually through increasing iterations (a frame for each individual iteration)
Also, an animation that draws the curve at the 13 or so iteration, but slowly to show that the curve never crosses itself.
