    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.

Nice! the i%2>0 can be further simplified to i%2 for another -2ch (applies to xen's too)

tried same with function.. still 140 ;) F=(e,d,a,b)=>x.fillRect(a,b,d,e);for(i=768;i--;x.fillStyle=hsla(${i+99*S(f)},99%,50%,.5)i<216?F(5,2e3,0,5*i,f=t*2):F(g=1080,5,5*i-g,0,f=t)

lol and now I wonder why I didnt just do this from beginning.. for(i=768;i--;x.fillStyle=hsla(${i+99*S(f)},99%,50%,.5)i<216?x.fillRect(0,5*i,2e3,5,f=t):x.fillRect(5*i-1080,0,5,1080,f=t*2)

based on the superformula https://en.wikipedia.org/wiki/Superformula, so playing around with the numbers some other shapes may apear.

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
