Hologram of Prince Charles?

The Hologram of Prince Charles was created by Musion Systems to project a life-size, three-dimensional image of the Prince onto the stage of the World Future Energy Summit in Abu Dhabi, in the United Arab Emirates. "His Royal Hologram" as he was dubbed by press, delivered a powerful speech on the environment to the world's leaders before vanishing into thin air. By using the Eyeliner System instead of attending the summit in person, he significantly reduced his carbon footprint, saving an estimated 20 tons of carbon waste.

Reduced his carbon footprint...hmmmm...right...
