The fifth annual Maker Faire drew tens of thousands of people to the county fairgrounds in San Mateo, Calif. Started by Make magazine for the Do-It-Yourself crowd, the event is a blend of wacky Burning Man style creativity, Rube Goldberg inventions, and technological marvels. Organizers estimate 95,000 people will attend by the end of this weekend. The 600 exhibits featured science projects by kids at local schools to well-financed projects by major corporations. All of them were celebrations of the can-do attitude that fuels Silicon Valley, breathing life into the innovative prototyping process and the culture of hacking.
