In many sci-fi movies, I have seen small phones or devices that projected holograms. Well, it turns out we may not be far from making this movie fantasy a reality!

Apple just patented a design for a mini-projector which they hope will eventually be in the ipad, iphone, and itouch. Not only will a hologram appear but it is said to be gesture-detecting! If ever becomes possible, I think it would be so cool!
