This is the fanciful Casa Batlló. I was surprised by every turn when I was inside, and it was always inspirational. I wonder whether you have ever played Myst? This place reminded me of Myst--except Gaudi had come up with the ideas so long ago--in 1877! And those designs were not only for beauty but large sums of functionality built-ins too. Simply moving cool air from room to room is stylish and unexpected.
