    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.

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.

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)

This is not very accurate of course, in particular it has quite bad iteration bias - and it's possible my math is wrong. It kinda looks right though I think.
