    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.

It's easier but there is a letter for each color instead of 3 letters per colo

Took some hints from d/11257 for the fire, but made it more minimal. Thanks to u/KilledByAPixel for the c.width&= trick that allowed to fit some nicer gradient and fire effect.
u/jellyedwards

That's incredible! How does the c.width&= trick work?
u/KilledByAPixel

c.width is 1920, 1920 & 8320 is 128, this way you don't need to write 128 for the width
u/tomxor

This is a bit verbose, but I found it easier to understand in binary: 1920 == 0b0000011110000000; 8320 == (8192 | 128); 8320 == 0b0010000010000000; (1920 & 8320) == 0b0000000010000000. In other words i needs to be roughly 8e3 to fill the screen, 8192 (the 14th bit) is not in 1920 so we can use it without affecting w. w needs to be quite small, 128 (the 8th bit) is the lowest bit available in 1920, which is why it's produced with AND.
u/magna

This is nuts.

damn damn damn... wonder what is the space between the two = after for(c.width| if I replace it by a normal space it kills the dweet :|
u/danny@hille.dk

+(+!+[]+[+[]]) is a slightly less verbose way to write 10, withou using any digits
u/danny@hille.dk

for(c.width|=ﾠ=ㅤ=+(+!+[]+[+[]]) ,x.scale(ﾠ,ﾠ);--ㅤ; ) x.fillRect(S(t)*(ﾠ+ﾠ+ﾠ)+ﾠ*ㅤ+ﾠ+ﾠ+ﾠ+ﾠ,ﾠ+ﾠ+ﾠ+ﾠ,ﾠ/(ﾠ/ﾠ+ﾠ/ﾠ),ﾠ+ﾠ)
u/danny@hille.dk

or less obfuscated : for(c.width|=a=i=+(+!+[]+[+[]]),x.scale(a,a);--i; ) x.fillRect(S(t)*(a+a+a)+a*i+a+a+a+a,a+a+a+a,a/(a/a+a/a),a+a)
