If you have an unmarked white van stalking your footsteps…

Or three burly agents with sunglasses talking into their collars watching your every move…

Or look up to find a whirling drone overhead eavesdropping on your conversation with your grandmother…

Watch your Step! You might just trip over some “Spy Rocks“. 

“Spy rocks”  been around since at least 2006 when the Russians discovered just such a device that the British had installed on Russian soil. The Russians weren’t happy to say the least and the indecent seems to have caused “Spy Rocks” to fall out of style. Until now anyway.   

“This week at the annual AUSA Army meeting in Washington, D.C., Lockheed Martin showcased developments in their surveillance technology called SPAN (Self-Powered Ad-hoc Network), a “covert, perpetually self-powered wireless sensor network” that can provide “unobtrusive, continuous surveillance” in units so small they can fit in a rock.” –Wired Magazine–

These sleuthing stones may not be under your feet today; Lockheed is still working on marketing the technology at the moment.

So the paranoid can keep their garden shovels in the shed for now. Still what will be next? Spy dirt? Trench coat Tree-trunks? Bugs with Bugs?
