We're big fans of the ludicrous and enigmatic @horse_ebooks Twitter account here, so discovering a horse_ebookmarklet that transforms your entire browser window into a tribute to the most engaging spam account we've ever seen was a great find. This bookmarklet was whipped together by Ben Nyberg, who expected users to enjoy it "for a good 20 minutes," but like all things horse_ebooks, it has some odd mass interest — Newsweek posted it to its Tumblr a few hours later. As for what it actually does, it uselessly replaces every image with the trademark horse_ebooks photo and inserts some excellent and strangely engaging gibberish. The utility is nill, but if you want a laugh, head to some of your favorite sites and enjoy the horse_ebooks takeover.
