Attended the Makers Fair today and was blown away by the open hardware and 3d printing progress. You can build anything from replicas of your face or rocket ships. Companies now offer complete manufacturing services so that you only upload a file and everything will be built for you. The maker movement will continue to be the engine of America. Here are some pics from the event.
There was a focus on developing standardized parts that would work with many other products and uses. This contrasts the traditional proprietary approach where companies try to make their systems as incompatible as possible. You've got to love the open minds.
As seen below there were robot petting zoo's, sun cooked pop corn, bee farms, solar bike trailers laser cut furniture. Well worth the full day.
