A couple of years back I posted about Napster Fabbing, the fabrication of 3D objects and transmitting the instructions for doing so across the Internet (the page I linked to is broken, but the Way Back Machine has a copy). New Scientist has an article about recent progress in fabbing technology. An object is created with its electronics embedded as part of the bodywork, a technology apparently known as "flexonics." However, this does mean that these objects are disposable, as it's practically impossible to fix any broken electronics. (via BoingBoing).
