During Earth Hour a fleet of 30 quadcopters took to the skies above London’s Tower Bridge, formed in the shape of the Star Trek emblem to advertise the new movie.
All 30 of the ASCTEC Hummingbirds were kitted out with a bright LED lamp and controlled by a central computer. Somehow the system actually worked really well given the beautiful London weather. Check out the video below showing the flight with some clips from the new film, Star Trek: Into Darkness mixed in. [engadget]
