I wonder if you could convert it to colour as well, if you changed the rule from a single thread for the whole thing to three threads for the whole thing (CMY). Might be quite an interesting effect since you'd need to sort of "smudge" colours across the image the same way you're essentially smudging the blacks.
Edit: Wait a minute, actually it wouldn't work because you can't combine colours. Put magenta thread on top of cyan and you'd get... magenta.
EDIT: Ok, it's a knitting loom (not a weaving loom), but the artist still isn't "knitting" using it.
It's hard to take this assertion at face value. Compare that to what a human go player can do vs. a computer. (2 billion computations would be on the order of seconds on a normal computer)
Still a cool project!
Also, it's fine to repost a story if it's good for HN and hasn't had attention yet. Otherwise too many great submissions would languish unseen. This is important enough to be in HN's FAQ: https://news.ycombinator.com/newsfaq.html.
And it's still a bad title given the content.
