Cool house by Koolhaas

The architect Rem Koolhaas designed Seattle's central library, a large building of non traditional angles and glass skin, a beauty of architecture, and a city center for intellectual inquiry.
It was described as "fun on a grand scale" and it certainly was, I highly recommend to visit this cool house with 40 feet high ceilings, neon yellow escalators, and a reading room just under the glass ceiling.
