Practicing graphical debugging using visualizations of the Hilbert curve

There's a very simple trick to dealing with these sort of recursive fractals: use logo/turtle graphics.

The reason is the angles stay the same, and you're making local decisions based on scale as to if you skip over something because it's too small, in order to avoid the problem of https://en.wikipedia.org/wiki/Coastline_paradox#Measuring_a_...
