After making a toy REPL yesterday, I realized that I could use it to pass device arguments, like screen drawing functions to evaluate, so I pushed it a bit further. Pressing ctrl+p, evaluates the file, selecting a bit of text evaluates only the selection:
left | bicycle
Altogether, left(11kb) and bicycle(6kb) make for a 17kb creative coding canvas.
