Original idea involved mouse controls, but I was unlucky golfing it.

Clean Long Trails #Default - demo of technique to fully fade off trails

u/sigveseb

Nice! Looks clean. What's the technique though? So hard to read compressed code on mobile!
u/KilledByAPixel

use difference with white to invert, then lighter with dark grey to make trails, then difference with white again to invert back
