The ubiquitous Apple Preview JPEG icon is symbolic computer shorthand for an image, but artist Alan Belcher has turned the humble vacation shot into what he calls "the ultimate 'photo-object.'" ______.jpg is a series of 125 ceramic icons, manufactured in China, then signed and dated. According to Belcher, it's "solidified its default icon into a standard image surrogate," turning it from background noise into a central object of focus. It's currently being shown at the Marianne Boesky Gallery in Manhattan, but hopefully at least one of the pieces will eventually end up in a massive three-dimensional OS X desktop.
