I don't even ... this is so cool, like a forest
u/pavel

This thing ((i&2)-1)*(2+i%7) takes so many characters. If somebody can figure out a shorter way to generate random-ish positive and negative numbers that aren't too close to zero that would be awesome. 7*C(i) is almost perfect but gets close to zero so you'd have trees on the path.
u/pavel

Oh! 3/C(i) works well here, but has no bound which will be an issue in other contexts.
