A Moore space-filling looping curve drawn with an implementation of an L-system renderer.
The Moore curve is a looping variation of a Hilbert curve, obtained by justaxposing 4 Hilbert curves. The last and the first point could be connected in order to draw a closed line.
The L-system rules are the same defined for the Hilbert curve, but the axiom is different.
The drawing of the line is animated using Mike Bostock's stroke dash interpolation.
