3D Video That R2D2 Produces
You’ll likely remember Princess Leia’s message for Obi-Wan Kenobi if you’re a big Star Wars universe fan. She has R2D2 track down the Jedi General and must deliver the message for aid that the Princess was in desperate need of. She says “help us Obi-Wan Kenobi, you’re my only hope.” You’ll see from the way the message is presented that R2D2 is using a sort of holographic video. However, this is not a hologram at all honestly. Technically, the droid was using a free-floating 3D video. This does not actually exist today but many believe it one day will.
