    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.

When browsers catch up, we can do a**b instead of Math.pow(a,b)
u/rep_movsd

FWIW double star exponentiation works on all current browsers I think

A 2 color plasma, couldnt fit the 3:d color

u/icecuber

Can you fit the 3:d color with this (reduced 21 bytes)? a=c.width=99;d=x.getImageData(0,0,a,a);for(i=3e4;i--;)d.data[i]=i%396+[b=S(i/5e3+t),-b,,i][i%4]*a;x.putImageData(d,0,0)
u/New_Core

nice.. that is much better
u/New_Core

a 3 color test added on icecubers code a=c.width=99;d=x.getImageData(0,0,a,a);for(i=3e4;i--;)d.data[i]=i%396+[S(q=i/5e3+t)*0.6,S(q+t)*0.3,S(q+t*4),i][i%4]*a;x.putImageData(d,0,0)
u/iverjo

Nice :) I find your attempt at plasma better than mine: Btw, you can replace 0.6 with .6 and similarly for 0.3

Cool, that almost looks like 3D!
u/lionleaf

This doesn't work on my Macbook with chrome for some reason.
u/New_Core

can it be the translation? if you put 0 in last number of translation and set the last number in code to 500, do you see something then,, or remove the translation and keep the 500 at the end of code,
u/lionleaf

Turns out any font size above 250 doesn't show up. 250 works fine though. Nice effect!
u/New_Core
