You’ve probably heard of the @Horse_ebooks Twitter account. If you haven’t, why not? Unlike other bots on Twitter, @Horse_ebooks sends out cryptic messages that have oddly mesmerised the internet. @Fart says it best:
@Horse_ebooks is a Twitter bot designed and automated by apparently some Russian guy to sell worthless, horrible ebooks about horses. In order to avoid being detected as a spam bot, it occasionally posts a text snippet or two from one of its ebooks, chosen at random. I will never buy an ebook from it, but I will follow this Twitter account until I die or horses become extinct, whichever comes first.
Now, Ben Nyberg has developed a bookmarklet to spread the @Horse_ebooks hilarity all over the internet. When the Javascript is run, every image on a page becomes the trademark horse and all the text becomes delightful gibberish. Nyberg himself expected this to amuse people for about 20 minutes, but all I know is that I am doing it to every site I see. Here are some examples.
So, what are you waiting for? Install the bookmarklet and try it yourself.
