The holographic video effect associated with "Star Wars" served as a technological tool for CNN during its 2008 Election Night coverage. CNN reporter Jessica Yellin and musician will.i.am looked as though they were in the network's New York City studios talking face-to-face with hosts Anderson Cooper and Wolf Blitzer, when in reality, they were in Chicago at Barack Obama's rally. The process involved Yellin and will.i.am standing in front of a blue screen in a special tent, while being shot by 35 HD cameras.
