Get ready for images projected in mid-air to start appearing in the next few years.
According to pop culture, weren't there supposed to be more holograms by now? The 1970s and '80s were full of holographic wishes. Back to the Future II told us that we'd have holographic movie trailers. A major Star Wars plot point involved a holographic Princess Leia. Even erstwhile cartoon pop star Jem's backup band was called The Holograms. But in the 30+ years that your correspondent here has been alive — with the exception of a quasi-holographic Tupac Shakur at Coachella 2012 — we've been stuck with either tacky 2D holograms or projections onto gauze.
