    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.

pretty sure it's not possible in 140 bytes, but anything resembling a voronoi diagram would be peachy.

Candy Falls - Requires Chrome

u/magna

Starting off with a blank canvas, I introduce some artifacts by damaging the JPEG export. And then the rest comes through an interesting interplay of JPEG artifacts and sepia filter artifacts, and stretching the image while pasting it back.
u/magna

Seems to be broken on latest version on Chrome.

Urban Pollution

u/SpecialAgent

This is a very nice effect, my browser ran out of memory after a short while though. ;)
u/iverjo

Haven't seen this technique before. How does it work?
u/magna

@iverjo: I keep exporting the canvas as base-64 JPEG and randomly screwing up with the data at a particular range that gives this effect while keeping the JPEG intact. Prior art: https://github.com/snorpey/jpg-glitch
