amputect on HNThanks, please consider sharing your pinwheel, I'm sure it was awesome to make too! You're touching on an important point. I tried to figure out CFR[] by trial and error and it…
omneity on HNThis is very neat, the minimalist approach has a nice aesthetic and some of the examples here are way beyond what I thought you could do with it.
jacquesm on HNThis is super fun to play with. Adding instructions at different points in this pattern generates some very cool overlay effects.…

From 2 comments
Looks great, congrats! Feature request: dedicated command for “forward without color”. Perhaps “L”, as in “lifting the pen”? I know black on black is treated the same, but I…
merelysounds on HNSome ideas I had after playing a bit more: - If you raised the bit limit and added a "skip" option (ability the move cursor forward without drawing) you could potentially render…

Questions
Is there a canvas-completeness measure analogous to Turing completeness?
From 1 comment
Is there a measure of something being "canvas complete" where you can construct "any bitmap" given it? Analogous to Turing complete but limited to drawing on a bitmap canvas.…
