    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.

Remixed from @micahcowan's https://www.dwitter.net/d/8781

u/davidsharp

swap .7 for speed, for crazy things like:with(x)for(i=n=90;--i;)F=(f,m)=>Math.abs(m-t*.4*f(i*1.5/n)*2e3%(2*m)),font='90px a',fillText('🌚🌝🍀'.substr((i%3)*2,2),F(C,1920),F(S,1e3))
u/micahcowan

Using u/magna's [...font] trick in d/8783, and removing an extra invisible character that appears in the list of balls (VARIATION SELECTOR - its absence may change the ball look for some people? didn't for me), it became possible to restore the screen-clearing. with(x)for(c.width|=i=n=23;--i;)F=(f,m)=>Math.abs(m-t*.7*f(i*1.5/n)*2e3%(2*m)),fillText([...font='90px ⚽🏀🏈'][5+i%3],F(C,1920),F(S,1e3))
u/davidsharp

That's a really neat trick 👌

Ha! Nice. 😀
u/micahcowan

Your use of ... '5em 🅓🅦🅘🅣🅣🅔🅡' to automagically limit it to one character, blew my damn mind. Is that your innovation, or did you get it from another? The useless JS things I learn here 😁
u/micahcowan

Wait, I'm amazed it even works, since those are each two chars in UTF-16. I thought JS deals in UTF-16, not -32? Is string subscripting more magical than I supposed? Time to go fishing through Ecma-262...
u/firegodjr

He's turning it into an array first, so the individual chars still act individually, and not as two UTF-16 chars. Array[x] works, String[x] only supports UTF-16.
u/micahcowan

Awesome, thanks. Had just figured that out when I refreshed the page to see if someone said that, heh!
u/micahcowan

You can see what's happening more clearly if you change 2e3 to 5e2. It's also interesting to set n=8, but then you also want to change 🅓🅦🅘🅣🅣🅔🅡 to 🅡🅓🅦🅘🅣🅣🅔
u/magna

@micahcowan It's a culmination of 1) spread syntax 2) using bullshit strings as font names that I've learned from others :)
