This week’s addition to the annals of pointless-but-wonderful technology: yooouuutuuube.com, a digital filter through which an ordinary youtube clip can be transformed into a trance-inducing cascade of the clip’s individual frames, to mesmerizing effect. So mesmerizing, in fact, that I recommend you don’t visit the site at work (unless you’re willing to explain to your boss why you’ve been staring at thousands of tiny “Alice in Wonderland” tiles for the last three hours). Down the rabbit hole, indeed.
