Tristan sez, "Open Source Ecology is a social enterprise based in Missouri. We develop open source machines that can be made for a fraction of commercial costs, and share our designs on the Internet for free. We've just designed version 4.0 of our compressed earth brick press, the Liberator. With this machine, anyone can make solid, 'dirt cheap' structures from the earth beneath their feet. This linked video shows the evolution of the CEB press from 2007-2012."
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
