    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.

There is a technique called neuroevolution (search for Evolving Virtual Creatures, by Karl Sims and also AI Learning to Walk And Run With Neuroevolution) where this kind of body movement spontaneously appears after the evolution of a genetic algorithm.

safer for editing #webgl

u/IV

manga's original is grand, this is safer than my previous attempt in terms of editing and not getting errors which cause a reload :)
u/IV

the prblem with this is that youd have to clear both contexts which costs more bytes

function u(t) {

t||c.replaceWith(g=c.cloneNode());
with(g.getContext('webgl'))(clearColor(C(t),0,S(t),1),clear(16384))

testing remix of d/1948

u/IV

correction: remix of d/19498. The problem with this is in replacing the canvas. Any attempt at a remix will fail to get the context. But it is shortest :D
u/nikoloffgeorgi

u/IV that's really cool. i wonder if anything beyond animating the color uniformly can be done within 140 chars
u/IV

nothing you cant do better with the canvas. try this: with(c.getContext('webgl'))(enable(0x0C11),scissor(i,i,i,i),clearColor(C(t),S(t),t,1),clear(16384))
u/IV

what we need is a glitter, with a quad shader set up and then we can play with 140 chars of a fragment main

u/nikoloffgeorgi game-on! i did this: d/19541
