Forward-looking: A team of scientists has successfully demonstrated the world's first interactive 3D holographic display, enabling users to physically interact with virtual light projections. If commercialized, this technology could be immensely useful in education – just to name one example.

In brief: Those Princess Leia holograms seen in Star Wars still require some ingenious scientific breakthrough we haven't quite cracked yet. But tech companies are becoming smarter, using existing technologies to create holographic effects. Panasonic is one of them, and has cleverly repurposed part of its outdoor cooling lineup to create a wild new visual display system that you can walk through.
