    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 ;)

Intense!
u/lionleaf

Sweet. A combination of #93 ( http://dweet.lionleaf.org/id/93?autoplay=1 ) and #143 ( http://dweet.lionleaf.org/id/143?autoplay=1 )?
u/lionleaf

(Yes. Linking to dweets from comments should be done in some clever way....)
u/iverjo

Yes, it's inspired by those two, but the half of the code is also based on http://dweet.lionleaf.org/id/80?autoplay=1
