"A house with curved walls is visible from Highway 280. While it seems like a house out of the Flintstones, it's actually an experimental house built in 1976, with rooms in which every surface is rounded. Designed by architect William Nicholson, the house looks a bit like a series of inflated balloons, which makes sense, since this is how it was built. Steel rebar and wire mesh frames were constructed over large inflated balloons and sprayed with gunite, also known as shotcrete. Basically just a concrete sprayed at a high velocity, gunit/shotcrete was, strangely enough, invented by famous Natural History Museum taxidermist Carl Aikely to help fill plaster animal models." - Steven Perez from Bookmarklet
