    Thanks!

    First thing I thought of when I saw Yonatans! Such a great team effort, the original idea, lots of golfing and these two finishing touches.
  • u/rep_movsd
    Fantastic
  • u/rep_movsd
    Now add color 😂

    oooooh, I love dithering! Nice one!
  • u/tomxor
    me too :) I didn't realise how simple the algorithm was before no, and it can be done in a single pass because it's only half a 2d kernel. Tweaking the coefficients (*R) can be fun, e.g 7*R=>5*R, 3*R=>5*R better preserves the dark and light areas in this image.
  • u/magna
    Wow
  • u/sigveseb
    Very nice!

  • Animated sprite silhouettes! (crawling)

    Adding a #time dimension to an old dweet of mine, by rethinking it a bit :)
  • u/rep_movsd
    Amazing
  • u/rep_movsd
    Looks like some of your earliest dweets dont render anymore on the new dwitter shim code
  • u/FireFly
    hmm, they seem to work fine for me :o (in Firefox)
  • u/rep_movsd
    Must be Chromium issues then
