H.P. to Report an Advance in Adaptable Circuitry - New York Times

Fascinating... 

Hewlett-Packard researchers have developed a novel way to create flexible electronic circuits that could make it routine by the end of the decade to modify and upgrade the circuitry in computer-based consumer products even after they have been sold.

The technology grows out of an advance in nanocomputing, which involves creating circuitry on a molecular scale and making it interact with today’s silicon wires and transistors.
