This is an unbuilt design by Frank Lloyd Wright called the Mile High Illinois "Project" and although never built it is seen as an inspiration to architecture students. I visited Frank Lloyd Wright's house and studio in Oak Park near Chicago and was amazed at the level of detail he went too to make sure his vision of the world was realised. He designed furniture as well as the building and his home has a very special feeling to it and his studio was an inspirational workplace that really thought not just of the architects and their working environment but of the whole impression it would make on clients.
This paper bookmark reminds me of that visit and his designs.
