    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.

Yeah, I came up with this trying to figure out how to implement a starfield type thing

note to future self... this is some kind of weird combination of interference patterns between waves, and circle-squares fractals ....to see whats going on, start out with fillstyle=R(B%256,0,0) then work from there.

in other words, it's not drawing the "lines of force", those lines are an artefact of the remainders of the 'quadrance' (squared distance) between the two black balls

Cool! Change first line to c.style.background=R(0) to get it done in 137 chars :)

cheers! didn't think of that :D

You can reduce to 136 actually! c.style.background=R()
