A minimum of words and an abundance of photos demonstrate how a group of teenagers in a nameless community built a geodesic dome based on Buckminster Fuller's icosahedron. (You can test the principle with ice cream sticks.) Between acquiring park department land and a city building permit one June and dedicating their clubhouse a year later, the teenagers dug the foundation, nailed floorboards, built up a framework of triangles, etc. -- sometimes discouraged as when several days' work had to be torn down and begun again, sometimes so enthusiastic that they rigged up floodlights and worked into the night. The dome builders exhibit so much enjoyment despite their evident hard work and so much satisfaction at its completion that we can only wonder why this isn't a more common summer project. Very likely after this book gets around it will be.
