Floating 3D video shows 'Star Wars' holograms are closer than we think

Thanks to Princess Leia's famous Star Wars plea, true holograms rank just behind flying cars as tech we want, nay deserve to have in our lifetimes -- and Tupac-style flimflam won't cut it. Now, an exhibition from artists Chris Helson and Sarah Jackets whimsically called "Help Me Obi" projects objects as large as 30cm (12-inches) in space. Visible from any angle in the room, the subjects include a newborn baby and NASA's Voyager 1 space probe. The creators are quick to point out that the machine doesn't create a true hologram, but rather a "360-degree video object." We take that to mean that it's more like a floating 3D movie that looks the same from any angle, rather than a true holographic object you can study from all sides. Since they're seeking a patent, Helson and Jackets are coy about exactly how it works, but say that there's nothing else quite like it (that they know of). If you're in the Edinburgh, Scotland area between July 31st and August 30th, you can judge for yourself at the Alt-W exhibition.
