The whole idea of all these long tunnels — the show is really a show of corridors — is another way of mediating temporality."

Eliasson's work is concerned with the act of engaging in the present moment. His car, Your Mobile Expectations: BMW H2R Project, for instance, is an iced vehicle, presented as the separate exhibition "Your Tempo" in a room-sized freezer that chills to 14 degrees Fahrenheit.

The vehicle is presented by the museum's Department of Architecture and Design, attesting to the latitude of Eliasson's work, which has been seen through the lenses of art, fashion, architecture, design, and environmentalism. He emphatically stresses the means. "I don't think art is that fragile," he said. "Art can easily go out and work like a virus."
