    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.

Great!
u/@noel

u/magna Thanks, but I made it on a slow PC, now that I'm watching this at home it's way too fast. Is there a way to handle this in code?
u/vain

@noel:
u/vain

@noel: i'm not really sure. But i think the best way to get it work same speed on all PCs it to use t (timer). Btw, the function u(t){your code} will be called 60 times per second. So using d-=4 should run same speed on all fast PCs - but slow down on older slower PCs.
u/vain

Btw, it looks really cool with this green shining spikes.
u/joeytwiddle

I like it, running fast or slow! Viewers can always add t/=2;

VHS 📼 #default + horizontal shift from noise

u/KilledByAPixel

nice, yeah that looks a bit more realistic!
u/tomxor

The noise on this is really good, I tried to find redundant bits to remove but everything you included adds to the realism.
u/KilledByAPixel

I don't know how I came up with this, was going through some of my old abandoned sketches and found this minus the default

#DooM 2.5D #bumpmap textures

u/tomxor

Same concept of XY displacement, but X displacement needs to be inverted when a surface is aligned along Z to give the illusion of the light comming from the observer. Completely unrealistic lighting tricks.

Golfed fire suggestion by u/deobfuscate using a single x.fillStyle instead of separate ones for the black background and colored pixels.
