    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.

#default Floyd–Steinberg #dithering

u/ciaccodavide

oooooh, I love dithering! Nice one!
u/tomxor

me too :) I didn't realise how simple the algorithm was before no, and it can be done in a single pass because it's only half a 2d kernel. Tweaking the coefficients (*R) can be fun, e.g 7*R=>5*R, 3*R=>5*R better preserves the dark and light areas in this image.

Text positioning tweaked on a Chrome on macOS, so may look screwed up on other browsers.
u/magna

Also, holy shit. Look at those artifacts around the skunk. Who at Apple cleaned that image?
u/magna

*Apple -> Chrome/Google? I don't know who is responsible for the emojis :)
u/mxfh

Lol. Apple Skunkworks I suppose. dwitter is a whole argument while real other browsers should be enforced to be allowed on iOS.

Safari/webkit is the new IE in terms of browser stagnation and bugs, i come to dwitter to not care about it :)
