The holographic technology startup Provision 3D Media has successfully produced 3D floating virtual images up to 52 inches large, and now it's setting out to develop a working life-sized hologram. The startup is trying to raise $950,000 on Kickstarter to develop and test the prototype. "From the moment Princess Leia materialized in 1977, Holograms would forever be tied to the vision of our future," the Kickstarter page says. "Science Fiction has shown us what's next. Now it's time to make it happen."
