Matthew Barney's Cremaster Cycle Multimedia artist Matthew Barney, 36, is almost universally fawned over by critics and is hailed as the most important artist to come along in years. In a stunning installation at NYC's Guggenheim Museum, he's made the museum into a bit player in his massive gesamtkunstwerk. And now this gorgeous website ups the ante on Flash-based sites. In addition to all this, the soundtracks from his Cremaster series by Jonathan Bepler are breaking new ground in modern composition. Oh, yeah, Matthew Barney is the dad of Bjork's child. Where does it end?
