"Notion Motion" is Olafur Elisasson's gorgeous 2005 art installation based on the interaction of water, light, and the viewer of the work. It's an amazing work, but how do you install something like this in a new location? How can the work be preserved over the longterm? The documentary above, "Installation Art: Who Cares?" explores this challenge from the perspective of museums and art conservators.
How to preserve and reinstall the work Notion Motion by Olafur Eliasson: 1.500 m2 of water, light and movement? What about works that are based on outdated technology? A large group of experts worked on the restoration of Exchange Fields, an interactive video-installation by Bill Seaman. Despite the fact that the work is only ten years old, it had to be completely restored and digitalized. And the artist Tino Sehgal doesn't allow any form of documentation of his works. Tate London acquired his performance This Is Propaganda in 2005. Will Tate be able to keep on showing this work to the public?"Installation Art: Who Cares?" (Thanks, Brenda Tucker!)
