    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.

Two interesting functions. T(C(x)) in particular looks a lot like a rounded triangle wave, which is pretty handy… mostly posting this as a meta-dweet/for reference. :)

feature request: posting anonymously...

u/lionleaf

Why not just create a pseudonym to post with? Or do you mean to make it quicker for new people to post something? I'm afraid it would just get filled with spambots
u/SpecialAgent

nice car chase. registration keeps the quality of dwits decent, imho.
u/kchplr

I was thinking about posting anonymously once you're registred, but it was mostly a joke given I'm not so glad with the outcome of this one. :D..

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.
