This past weekend, a new installation by contemporary artist Olafur Eliasson made its way into San Francisco's Museum of Modern Art. It's a project he's undertaken as a cooperative effort with BMW's Art Car program. Essentially, the artist has re-envisioned BMW's H2R race car in such a manner as to signify the fraught relationship between global warming and the automotive industry. It's as though he's turned the roadster into something of a technological glacier.
