Colorado's real capitol dome is in trouble. It is rusting, rotting and cracking, and fixing it will cost millions. But a scale model of the building, made entirely of canned goods, is doing just fine. Located inside the dome museum — known as Mr. Brown's Attic — the replica is a version of one originally created for the 2004 People's Fair by Intergroup Architects of Littleton as part of Canstruction, a yearly contest held by the Society for Design Administration. Made from a variety of containers, including soup and tomato sauce cans and sardine tins, it's topped by a plastic water bottle. Canstruction projects are typically built as fundraisers, and the food is then donated to food banks, but this one is on permanent display — which may be more than we can say for the real thing.
