What was your first impression when you saw the Princess Leia hologram in Star Wars? Seemed pretty crazy at the time. How in the world (errr galaxy far far away) did they get a 3D video to be played from a droid? It does not seem quite as crazy 35 years later. Hologram technology (a.k.a. holography) currently gets used in security (currency, drivers licenses), art, data storage and many other areas. Now it is even involved in games. Yes, games!
