Dragon curve generator tool
What is a dragon curve generator?

This tool draws dragon curves — self-similar, space-filling, fractal-like curves. The dragon curve is also known as Harter-Banks-Heighway curve or Jurassic Park curve. We're generating it using L-system rules but another way to generate it by using a paperfolding sequence. You can change the color of the curve and its background and set the width and height of the space that curve fills. You can also specify how many iterations of the dragon curve to generate. Because computing the fractal is an expensive process, we limit it to 21 iterations. As computers get more powerful, we'll allow higher-order curves. Last but not least, you can specify curve's thickness and add padding around the edges so it looks nicer. Mathabulous!
