    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.

Cityscape! At 170 chars I had it moving quickly, and with much, much better randomisation. To see the paralax work, multiply q=t*o by 10. I would have loved to have had a little car emoji too, but oh well, I'm still new. I've spent way too long trying to shorten this lol.

u/SpecialAgent

You can remove the brackets around r=(r*9e2) to gain an extra two characters, since both * and % fall in the same operator precedence group, then q=t*9 works. Good dwit!
u/Renaud___

s=r/(w*99)*70 can be replaced by s=.7*r/w too it seem
u/SpecialAgent

correction, q=t*o*9 works
u/lionleaf

If you change the dweet itself you can post directly and it becomes a remix. Post the moving one!
u/5Mixer

Woah, thanks for the replies guys. I looked for ages and didn't spot those chars :) Remixed it moving faster.

How did you come up with this?

@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

Hi there :) I had to delete #1215 because it froze the browser (due to some excessively deep recursion or something). Here's the code, for reference: (F=Z=>{for(x.fillStyle=R(W=2/Z*1e3,W/2,W/1),i=Z*Z*2;n=i%Z,m=i/Z|0,i--;n%2^m%2&&x.fillRect((n-t%2-1)*W,(S(t)+m-1)*W,W,W));Z&&F(Z-5)})(36)//rm
