Gosper curve
SPACE-FILLING CURVE WHOSE LIMIT SET IS REP-7
Flowsnake; Gosper island; Peano-Gosper curve
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 whose limit set is rep-7. It is a fractal curve similar in its construction to the dragon curve and the Hilbert curve.
