Flowsnake technical information The Flowsnake was invented by William Gosper. It is a space-filling fractal curve. "Space-filling" means that if this process were carried out infinitely, this curve would pass through every point in the region it occupies. It is a fractal in that if any "segment" is enlarged, it will be identical to the entire curve. This curve has a fractal dimension of log(3)/log(sqrt(7)) = ~1.129.
