About the fractal curve maker

Print the famous space-filling and fractal curves of mathematics as coasters, wall art or teaching models: Hilbert, Peano, dragon, Gosper, Koch, Sierpiński and more.

  • Raise the detail level until the lines are about to touch.
  • A base in one colour and the curve in another shows the pattern best.
  • Round the corners for a softer, flowing look.
