They say advertising’s an ephemeral medium, but I’m not so sure. I collect old library-bound volumes of Life magazine, and given proper care (and kept away from the razor-clutching hands of people who want to carve them up and sell them piecemeal on eBay) those magazines have some serious shelf life, and so do the bright colorful ads they contain. And there are any number of websites archiving film, TV and radio ads, from the Internet Archive on down. But an agency called Element Six Media is creating ads that really are ephemeral — as much so as melting snow and drifting sand. It may not be art, exactly, but it sure is arresting. And if the point of advertising is to get you to look, mission accomplished. (Via Inhabitat.)
