A bit modified iverjo's Choo choo: http://dweet.dwitter.net/id/342?autoplay=1

u/iverjo

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
