One of the challenges that geeks, inventors, hobbyists, hackers, burners, and artists who are trying to change the world face is finding a place to do their work. Ideally, it would have lots of equipment, supplies, and other geeks. Until the last year, they would have to set up their own workshop or beg for space at a machine shop. Now they can go and hang out at TechShop in Menlo Park, California.
