    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 👌

This is just the time rounded down in hours, there's a bunch of logic that could be golfed away if the clocks string was also golfed down (the first character of each emoji is the same, these also count against the 140 characters)

u/davidsharp

Darn, string should've been 🕛🕐🕑🕒🕓🕔🕕🕖🕗🕘🕙🕚
u/micahcowan

Pretty neat!The -1 doesn't work out for hours at 0 or 12. Could have added 23 (before the % 12) instead of subtracting 1 (or yeah, your string-based fix).

I think I fixed the string, and adjusted the numbers, but then undid a bunch of changes, including my string fix and adjusted the code for the broken string instead 🤦‍♂️
