I Only See Things When They Move

Eliasson was the subject of a large one-artist exhibition at the Museum of Modern Art in New York in 2008, including this work, which is owned by MOMA. I highly recommend MOMA.org Interactive Exhibitions: Take Your Time: Olafur Eliasson (2008), a website that offers extensive documentation of Eliasson's installations in the exhibition, including videos in which the artist describes his own work.
