After spending a weekend at Frankfurt's Ambiente consumer goods fair, courtesy of Messe Frankfurt, it seems to me that the design world is floating on a cloud. Arturo Alvarez did it first with his Nevo collection, and now designers worldwide are creating cloud-like light fixtures that create an ethereal, heavenly feel. From puffy, mashed-potato-shaped paper forms to plastic, marshmallow-like pendants, designers are putting their own spin on the style. It's a trend that doesn't seem to be going anywhere . . . it's just floating slowly by. Come along to cloud nine!
