After years of promises, it seems that holograms are finally starting to gain a little traction
, although the applications for the technology so far have been fairly limited. At least one company thinks that's about to change, however, with it now touting its retro-styled Holocube as an all-purpose solution for company's to advertise their products "like never before." Measuring about 20-inches square, the Holocube packs a 40GB hard drive for storing up to 18 hours of compressed video, which can magically float at 1080i resolution within the cube at the flick of a switch. Of course, the fact the company is targeting the device solely as a means of advertising should tell you something about the price (which is on a need to know basis, it seems). Still, it's a start, and we're guessing there are at least a few folks out there that'll snag one of these to fully round out their Star Wars-inspired home theater no matter what the cost. Head on past the break for some video of it in action.
