What is Fractal Gosper Curve Puzzle?

The Gosper curve, also known as the Peano-Gosper Curve, is a space-filling curve named after Bill Gosper, sometimes known as the flowsnake (a spoonerism of snowflake). It is a fractal curve that is built similarly to the dragon curve and the Hilbert curve.

The Gosper curve is also useful for hierarchical hexagonal clustering and indexing.

This is a space-filling fractal, sometimes known as a "flowsnake" as a play on the phrase "snowflake." The Gosper Curve, like the Dragon Curve, is a fractal because it is built by repeating a small fundamental shape.
