World's Smallest Computer Created - Yahoo! News: "Researchers recently unveiled the first complete millimeter-scale computing system that is about the size of the letter 'N' on the back of a penny (or about the same size as the letter in this sentence).

This tiniest computer to date is a prototype of an implantable eye pressure monitor for glaucoma patients. Key to this unit linking up with other computers to form wireless sensor networks is a compact radio that needs no tuning to find the right frequency.

One day, these Lilliputian computers could track pollution, monitor structural integrity, perform surveillance, or make virtually any object smart and traceable."
