    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.

adding x.globalCompositeOperation="lighter" in the loop makes it more metaball like.. but it gets to long and using ImageData even longer so.. ½ way ;)

A brute force approach to circle packing. A lot of thanks to jsgolf slack channel residents @xem and @qfox helped **a lot** reducing my original 167 characters attempt ( https://codegolf.tk/a/152 ), as in actually doing most of it. I honestly did not think reaching 140 bytes was possible.

u/Xen

done you a remix ;)
