    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.

Oops, busted? :P Actually it's almost identical to d/14830. Could be a freak coincidence. Genuinely interested if this was accidentally golfed backwards to the previous one :P

@KilledByAPixel - yeah - this particular one came out of an AI I trained - on your dweets, because you are my JS hero. Many apologies that I did not surface an attribution when posting, and I am a mere mortal in your presence
