Green Flag! . Select "n" on the slider and press the space bar. This curve exactly fills another curve "Gosper Island" (coastline of the island). Passes through each point only once (does not intersect) Gosper island - http://scratch.mit.edu/projects/42201356
The Peano-Gosper curve is a plane-filling function originally called a "flowsnake" by R. W. Gosper and M. Gardner. Mandelbrot subsequently coined the name Peano-Gosper curve. Two procedures were used recursive levorotatory and dextrorotatory. The Gosper curve, also known as Peano-Gosper Curve, named after Bill Gosper, also known as the flowsnake (a spoonerism of snowflake), is a space-filling curve. It is a fractal object similar in its construction to the dragon curve and the Hilbert curve.
