    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.

I plotted (shittily) all 28 unary functions: d/32414
u/lewdev

Thanks u/cantelope I didn't know about that one. u/magna your remix is awesome. I didn't know about all of those single-argument functions in Math. There's so much more JavaScript to learn!
u/magna

u/lewdev thanks for the inspiration!
