Sculptor Kenneth Snelson had a show last fall at New York City's Marlborough Gallery, and it didn't garner a single review. This may not seem surprising, given the crowded artistic field in New York, but Snelson is an unusual artist. Not only has he inspired a new field of engineering and a new understanding of cellular biology, his elegant sculptures are themselves scientific wonders. Their shiny metal rods, held together by networks of tensed aluminum wires, climb into the air at improbable angles, with an apparent disregard for gravity.
