Using multi-colored lights strung across the length of the upper walkway, technicians have created a gigantic interactive exhibit wherein sensors located at either end detect travelers' Bluetooth-enabled gadgets (cellphones, laptops, PDA's, etc.) and then track their progress in pseudo-real-time as they move across the bridge. Visually, the movement is represented by a uniquely-colored pixel appearing at more-or-less the same spot on the walkway as the device; to a faraway observer, it would look like this single &quot;pixel&quot; was making the journey from one end to the other. In order to ensure device anonymity, the Bluetooth sensors only send a derivative of each device's MAC address to the bridge's main controller, so consider this a <a target="_blank" href="http://www.engadget.com/search/?q=bluesnarf">Bluesnarfing</a> safe-zone. If you're in the area and want to check this out -- or love Bluetooth enough to buy a plane ticket (any BT fanboys out there?) -- you'd better hurry, as the project ends and the bridge goes dark tomorrow.<br /></div> </div> </div> </div> </div> en-US &copy;2005-7 Glen Campbell Mon, 13 Oct 2008 06:17:39 PDT Siteframe 5.0.5 webmaster@siteframe.org http://blogs.law.harvard.edu/tech/rss 30
