The incredible 3D projection system
From melting ice rinks to rippling chess boards, the stunning projection sequences used in sports have become just as much a spectacle as the game itself.
Katy Perry, for instance, stunned spectators when she used the technology during the Super Bowl XLIX to create the illusion that she was transported to a tropical island.
Now, developers of the system are hoping to advance projection technology so that the crowd can change what they are seeing on the court using their mobile phones.
