The ROM (Royal Ontario Museum) is going through a bit of a modernization to be completed by 2010. They took a very traditionally built museum and turned it into something hideous. It looks to me as if some architect simply got a giant lump of tin-foil and threw it into a model of the museum in frustration when he couldn't think of any good ideas, and then submitted that as his concept piece. When I visited the museum I wrote in their comments book next to a model of the yet-to-be-completed reconstruction, "this reveals that the age of great architecture is dead."
