    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.

There's a difference between Chrome/Firefox on both linux and windows. This should be seen as a lingering webbing line. Investigating...

A growing tree.

Viciously golfed thanks to u/FireFly and their JS golfing prowess.
u/trancor

I just facepalmed... !t is so much cheaper than t==0 (I've been using...).Well done on the mapped expansion, interesting way to generate a ton of objects.
