Jamie O'Shea is a conceptual artist. We've previously featured his bed, which is designed to be used standing up. More recently, he became interested in the role of knowledge in developing our technological civilization. Is knowledge alone enough, or are we dependent upon tools made by others? To find out, O'Shea decided to build a telegraph completely from scratch -- including the tools -- using only what he found in a New Jersey forest. At the link, you can watch a video of his attempt.
