Buckminster Fuller is one of my design heroes, and a true visionary with the guiding principle… “to make the world work for 100% of humanity, in the shortest possible time, through spontaneous cooperation without ecological offense or disadvantage of anyone.”
His creative legacy can clearly be seen in the annual Buckminster Fuller Challenge. Here is a nice article about it, and about Buckminster himself http://uspolitics.einnews.com/article/871391-hang-on-planet-earth-help-is-on-the-way
