Designer Nanette Lepore has begun testing interactive mirrors in her department at Bloomingdale's in New York. The mirrors are high-resolution digital screens that project digital outfits for potential buyers. The resulting image is then forwarded to a webpage where friends or the public can view and rate the outfit. It's a good effort to ride the social networking wave, but it's absolutely going to fail. Shopping with girlfriends is a social experience that can't be replaced with a computer. Plus I already invented an interactive mirror. You punch it when you're angry and then your fist bleeds. It's genius.
