    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.

I prefer this with a slower cycle by having t/99 instead of 9, but I couldn't find another place to drop a character

u/iverjo

You could move f= inside R, like this: c.width=198;a=6+C(t/9) for(i=-99;i<99;i+=a)for(j=-56;j<56;j+=a)k=i*j,x.fillStyle=R(f=k*k*(1+C(t)),f/9),x.fillRect(99+i,56+j,a*S(k),a*C(k))

For those who are wondering h is meant to just represent half the height of the screen. I just wound up using it in inappropriate places because it was roughly the right number for what I needed

Bah, and there I was thinking I'd got there first. I get crazy lag when trying to look back due to the infinite loading, so I've been unable to see what people have done already

How did you come up with this?
u/iverjo

@badthai: First I made a classic tunnel effect (like this: https://www.dwitter.net/d/205). Then I made several remixes of it by tweaking parameters. This was one of the results. See also https://www.dwitter.net/d/106
