The combination of quadrotors, LEDs, and GPS can make for an impressive light show! That was the case for the Starfleet logo from the Star Trek universe, which showed up over the Tower Bridge in London as a promotion for the new movie Star Trek: Into Darkness.
Ars Electronica Futurelab, the same outfit that illuminated the skies over Linz, Austria, last year, launched 30 quadrotors near London's Tower Bridge and flew in a formation that any Trekkie would salute.
The 30 LED-equipped AscTec Hummingbird quadcopters from Munich's Ascending Technologies hovered about 118 feet to 426 feet above Potters Fields Park and formed a Star Trek insignia to coincide with Earth Hour.
The batteries that powered the micro UAVs (unmanned aerial vehicles) were charged on the Austrian renewable energy grid, according to event sponsor Paramount Pictures.
