On election night 2008, CNN's Jessica Yellin temporarily transformed into Princess Leia, minus the hair buns. Standing in a specially designed tent in Chicago, Yellin, ringed by 35 high-def cameras, had a 3-D image of her body beamed to CNN headquarters in New York.
Despite what Wolf Blitzer says, it's not a true hologram. The image was not actually projected onto the floor of the CNN; it was inserted into the video feed. So in the video you see, Blitzer is actually speaking to an empty space.
