    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.

Precise paint. If you want to use it on fullscreen, change fs to 1

u/katkip

^ edit: isn't precise when fs=1
u/Fime

On mobile, at least in opera touch there is always an offset in dweets which use mousemove

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]]
