    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.

Very nice.

Very cool! To fix the y slope effects, just change "Y=i/96" to "Y=i/96|0".
u/lionleaf

u/vain : Quick tip: if you use beta.dwitter.net you can delete your own comments! (It's a new feature)
