    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.

oops, wet phone screen posted early. so you can add .1 as the fourth channel instead of using globalAlpha: R(r=(1+S(i/j+t*j*C(t*9)))*(b=128),C(r*S(t))*b,b-r,.1)

nice!
