Drawings by Paolo Soleri, who was also a proponent of Megastructures and specifically the concept of the Arcology as a working system, necessarily relating architecture and ecology. He is (and has been since the seventies) constructing an Arcology in the Nevada desert, called Arcosanti. I first became aware of the Arcology through Sim City 2000, which is proof that playing computer games is not a complete waste of time.
