We chase the sun, it chases us, but few buildings follow chase. Try to follow the sun, try to follow the shade, try to rotate, try to assemble triangles into shape. Try involves the inhabitant to engage in the definition of their own environment. Through the mobile nature of this rolling structure. By giving defined paths, strategies and systems for ventilation. The structure becomes a tool for the inhabitant. Rather than the human being the tool used by the architectural design of it's habitat.
