We are entering the 3D world in many ways. 2D will be archaic soon. Images, film, tv, holographics, games, printers, web (GE, 2L) etc. Now mobile phones will be entering this migration as well encompassing the content types in our near future. I guess this will bring new avenues for marketing, entertainment, networking as well as learning. More in this link on 3D images on mobile phones.
"Japanese mobile phones already let users shoot films
and share them with friends. It may not be long before the images go
another step -- becoming completely three-dimensional. Japan's Hitachi, Ltd. has developed a
lightweight 3D display that can potentially be adapted for mobile
devices such as telephones.
The gadget, using what is known as stereoscopic vision display,
weighs only one kilogram (2.2 pounds) and resembles an upside-down,
multiangular pyramid full of mirrors on top of a liquid crystal
Taking advantage of the portability of the display, the company expects it can be put to use to show museum pieces at schools so they will appear as if they are standing up right in front of students."
