I've stared at this for too long... don't think I can get it below 146 decompressed (with Z inlined). Would be rad if we could squeeze those last characters out though and get it down to 140 without compression :)
u/tomxor

I have an imperfect 142
u/Agnes

This is 145 but I don't remember if the new indexing is actually shorter or not than yours: for(i=w=128;i--;x.fillStyle=R(i%2?x.fillRect(X=i%16*64,Y=i*8&-w,m=X+Y&w,m)|w:x.fillText('♜♞♝♚♛♝♞♜♟ '[Y++%7?++Y%5?9:8:i/2%8],X,Y+w)))x.font="4cm'"

Dweet slideshow. Shows a new random dweet every 9 seconds starting at older dweets. Some dweets will break it since all changes are in global scope.

This is the best one because it shows them all!! I'm trying to figure out a way to extract which dweet number is playing at a given time (maybe using the debugger?)
u/AnnanFay

Thanks :) Developer Tools -> Network tab will display the requests. The latest request will be the one playing.
u/AnnanFay

There's a 150 byte version which displays IDs as error messages. (async I=>eval(T.L==I?T[I]:(T.L=I,T[I]=((await(await fetch(V=0|Math.random()*I*100)).text()).match(/u\(t.*([^]*?) }/)||(T.L=T))[1])))(1+t/9|0) throw V
u/garettridge

Brilliant! The network tab!
u/zanella

Every time I scroll through this dweet, I think "Funny, don't remember giving an awesome for this dweet". :D

Nice trick with the flipped drawImage!
u/jylikangas

Thanks! Here's two vultures without compression... 'for(c.width=i=-9;i++;)x.fillRect(X=99-C(t-=T/59)*(90+i*5),X/9+C(t*4)*(T=i+4)**2/5,5+(s=2+!T*4),s) x.scale(-.5,1) x.drawImage(c,-290,50)'

Here's a whol bunch of 'em for(c.width=i=-9;i++<9;)i<0?x.fillRect(X=99-C(t-=T/59)*(90+i*5),X/9+C(t*4)*(T=i+4)**2/5,5+(s=2+!T*4),s):x.scale(-.9,.9)|x.drawImage(c,-290,50)
