    fillText Y=i==52?Y-T:Y+T, but can't animate with this method. Don't think it's going to be possible in 140 ether.
  • u/DataMeta
    ugh yes. so satisfying
  • u/sigveseb
    very good, but the king and queen on one side are reversed!
  • u/tomxor
    oops good spot

    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'"

  • u/pavel
    font='4cm"'
  • u/FireFly
    ohh good one, didn't know about the font-family name trick
  • u/TGY
    now we need to combine 2 dweets into single XD
  • u/DataMeta
    fit them together with compression, but would be more interesting to jam it into 140 :)
  • u/FireFly
    I can do a full chess board in 151c currently, but it *would* be really satisfying to fit it into the 140c without compression tricks indeed

    Lol. Apple Skunkworks I suppose. dwitter is a whole argument while real other browsers should be enforced to be allowed on iOS.
  • u/rep_movsd
    Chromium doest show the skunk :(
  • u/tomxor
    Safari/webkit is the new IE in terms of browser stagnation and bugs, i come to dwitter to not care about it :)
  • u/mxfh
    ok, spotty alpha channels are not that rare: https://observablehq.com/@mxfh/emojis

  • Some nice math for the 270 initial radius: The half-height is 540, this must equal r+r/2+r/4+r/8+...=r(1+1/2+1/4+1/8+...). Think about the bit in the brackets in terms of pizzas. You have a whole pizza, plus half a pizza, plus a quarter (half the remaining half), plus an eighth (half the remaining), etc. You have two pizzas! So 540=r*2.

    Neat! Btw, -6c with these (if you want to try to fit more in, e.g. doing pieces instead): (j/w^i)%2 -> j+u&w; (i>>3)%8*w -> i*16&896
