The Force may not be with us, but what about the tech in 'Star Wars'?

Decades after 'Star Wars' made its debut in cinemas, has any of the franchise's iconic technology come even close to becoming real?

In 1977, Star Wars blew away audiences with faraway visions of lightsabers, droids and holograms. Decades later, has any of the franchise's iconic technology come even close to becoming real?

There are few film lines that are more iconic than "may the Force with you." Say it a few times fast (or make a young child say it a few times) and it can sound like "may the Fourth be with you."
