    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.

Nice ^^ I like how you used fromCodePoint instead of fromCharCode to shave bytes. Btw, you can replace (i?0:27) with !i*27 to make the code even shorter
u/sigveseb

for..of can make this quite a bit shorter! x.fillRect(i=0,87,W=c.width=310,3);x.font='49px A';for(a of'🚂🚃🚃🚃🚃🚃🚃')x.fillText(a,q=W-t%4*W+i++*46,90+S(q/15))

stiaje tried to create a dweet with unicode characters in the code, and it didn't work.. why does it work now? :D
u/iverjo

Maybe it was a problem with base64 encoding/decoding @ arkt.is/t/
