    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.

u/aleamb

nice!
u/DirtyDan

Don't know what I was thinking having "+960+C(t)*i" in the first arc parameter -_- ... 11 extra characters!
u/DirtyDan

nvm, the +960 was necessary, not the "+C(t)*i"... 7 extra characters.
u/Purpzie

This is so beautiful.

If you want to remix, for extra space delete "a=" and replace "(a<0?t:-t)" with t. That stuff just reverses the direction of the ripple depending on what side it's on.
