A team from Arizona State University animated the sky with 600 lighted drones in a spectacular show before more than 53,000 people at Mountain America Stadium on Saturday night.
The four- to five-minute drone show during halftime of the ASU football game was designed by three students and a professor in the Herberger Institute for Design and the Arts.
The drones danced in a space above the scoreboard that was as big as a 30-story building, swirling and zipping around to create a series of three-dimensional animations, including a drum, the ASU logo, a spinning pitchfork, Sparky and a gigantic football helmet.
