    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.

D: it's incredible. I still don't fully understand whats going on the begginning of the for.

Thanks! Touching the width ( or height ) of a canvas resets it. c.width|=i=48; ⇒ Sets i to 48. Does a binary OR of 48 on the width of the canvas and resets ( it mostly clears it ) the canvas

redrawing the canvas and initializing i, nice!

Hmm, why can one not do '🐸🌷☁️️'[k]? Is it simply because they are not single-byte characters?
u/p01

@iverjo: Exactly. Although I should have used [...'🐸🌷☁️️'][k] to save 3 bytes
