Not as good as the original 'Help me Obi Wan Kenobi' Princess Leia hologram projection in Star Wars, but at this rate it won't be long before high quality Princess Leia holograms become a reality - I'm still impressed by the 'Touchable Holography' demonstration from Tokyo in 2009:
Holographic projection opens up a world of possibilities. Once this hits high quality, 3D experiences projected from a computer could bring an entirely new dimension to the world in everything from communications to gaming to brand experiences and more!
