Nice! Any particular reason you didn't initialize i to 6e3? That'd take care of that gap you have in one of the tendrils

skoehler stole your dweet
u/warbino

ummmm someone stole your code............... his name is skoehler .
u/cantelope

@warbino, @thenize. this may be the last time you are reminded about the spirit of this platform. we do not dwell on "stealing" of code, as remixes are a provided function of the site. Your pattern of edge comments itself, since it continues, may be considered abuse. Unless you stop, there may be action.
