Fuller created numerous architectural designs, but is most famous for his geodesic dome... Montreal's well known and loved Biosphère (Expo 67) is one of my fave of his creations. He introduced synergetics, which he described as a 'metaphoric language for communicating experiences using geometric concepts'. Fuller also developed many ideas for practical, inexpensive shelter and transportation in cities... he was concerned about sustainability and about human survival yet remained optimistic about the future. As an early environmental activist, he was very aware of the planet's finite resources and promoted a principle that he termed "ephemeralization", which he coined to mean "doing more with less". He published 30 books, which documented his life and philosophies. The dude was rad.
