    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.

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

I like this, you can save a couple bytes: c.width^=0;for(i=24;i--;)for(j=24;j--;)s=S(t+=1.1)*((j+i&1)*2-1),x.setTransform(C(t),s,-s,C(t),i*99,j%12*99),x.fillRect(-9,-49,19,99)
