Seattle - the Library
While the staff aren't all that friendly - the new Seattle Public Library is great - skinned with glass to catch as much of the Seattle sun as possible, and well considered interior spaces and a unique flow through the stacks.
Curving through the center of the fourth floor is a vibrant red hall that feels like a combination of the klaxon red glare of a sci-fi space ship in trouble and a late 60's furniture set.
Glowing up the core of the library a neon yellow escalator contrasts to the white walls and brilliant fern patterned carpets. A variety of projections fill the great central atrium. They did not seem interactive.
Capping it all off - once you're on the top floor you realize the ceiling is padded - and filled with lights, fire extinguishers, and cameras.
