As Wikipedia describes it, "the Hilbert curve (also known as the Hilbert space-filling curve) is a continuous fractal space-filling curve first described by the German mathematician David Hilbert in 1891, as a variant of the space-filling Peano curves discovered by Giuseppe Peano in 1890." This is a maze in which the 4 levels follow the first 4 iterations of the fractal. .-' changelog '-. v1.0 - Added 4 levels following the first 4 iterations of the Hilbert Curve.
