    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

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
