World’s Smallest Combination Lock

From the Your Tax Dollars At Work Department:
Sandia Labs had developed the world’s smallest combination lock, and hopes to have a commercial partner lined up for distribution within two years, after they have completed refinement and reliability testing. Each of the six gears is only 300 microns across, about as big as a period in standard newspaper text. The lock will be marketed at the computer industry.
