  • Lost At Sea 🏊‍♂️
  • u/UEZ
    I like the very smooth waves :-)
  • u/taupelink
    wow!
  • u/pavel
    Very nice vibe. You can do x.fillStyle='#025'+j for the fade to avoid the low rez.
  • u/pavel
    Hm your sub-pixel trick works even at 1:1 rez... neat

  • u/eyaler
    i love it, but noob question - the decoded string is the same length. so why encode?
  • u/eyaler
    z=.61+Math.random()/1e3;for(m=t?0:2e4;m-->1e4;x.fill())x.beginPath(x.fillStyle=R(j=m**(g=m%z),j*.8,j*.75,q=S(m)**4)),x[q>.5?'arc':'rect']((m%13-.5)*160,(j|0)%9*135,40/q,j,j-z/g)
  • u/taupelink
    thank you! i think it's 177 chars when uncompressed
  • u/tomxor
    The funny thing is that it's actually much much longer when you count in bytes. The uncompressed is 178 bytes because it's pure ASCII and the compressed is 319 bytes due to all the multi-byte unicode. (you can get the UTF8 encoded byte length using new TextEncoder().encode('code').length

  • Mountains at Sunrise

    Getting a bit of a celestial feeling from the sunrise. Maybe sunrise on a distant moon.
