I've seen this on Twitter, then on the Reddit homepage, now it's in HN's #1 spot. What's going on, how is this new? I've seen an article on how to do this years ago on HN. It's a funny thing to do, just like the Google homepage doodles or telnet towel.blinkenlights.nl (if I remember correctly, that streams ASCII Star Wars to you)... what's special about bad.horse (besides the relatively new GTLD)?
