Press the green flag to draw the Gosper curve. Wait a few seconds to see several levels of complexity.
The "Gosper curve" is also known as the "Peano-Gosper curve". It is a fractal, and an open curve that fills the space, similar to the Hilbert curve. Notice that if we give color to the shapes, we obtain interesting patterns, where we can appreciate that it forms hexagonal clusters formed by 7 tiling regions. There is a whole family of space-filling curves like this one, which is worth exploring.
