    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.

Yeah, I have an endless remix chain on this lol. Not to mention it's not even shortened slightly bit
u/pythech

Maybe we can mix it with different things or make more advanced animations and so on. It has room for that

Aaand... I just deleted it accidentally, great!
