It's a kind of validation when our past visions of the future and the present collide, reminding us that things we thought were possible back then actually were within reach. Take, for example, Tokyo-based Burton's Aerial 3D technology. The company claims it's the first 3-D tech that casts three-dimensional objects in mid-air without using any kind of screen. It recalls that scene in Star Wars where the crustacean-faced guy is planning the rebel battleplan around his big holographic table. And it's here today.
