    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.

Sum of three sine waves. By modifying w, you can try any combination of sine waves.

u/mildlybean

w=[[3,25,3],[6,25,2],[9,25,1]] is cool
u/mildlybean

So is w=[[4,20,-2],[2,40,2]]
