Remember the iconic scene from Star Wars, in which R2-D2 projects a hologram of Princess Leia saying, “Help me Obi-Wan Kenobi, you’re my only hope?” That’s kind of what researchers at Southern Methodist University, Dallas have demonstrated with new 3D projection technology that allows for the creation of three-dimensional light structures, viewable from 360 degrees. Just don’t you dare call them holograms!
