"Caltech researchers have demonstrated a chip they hope will one day let smartphones act as projectors."
Really? So what do you call this:
Beam Projector Smartphone
Projection with 15 Lumen DLP (Digital Light Projector)
Your smartphone's built-in projector gives you the freedom to share - to really share - all kinds of contents with your friends virtually anywhere. Stunningly good definition with a gradated throw up to 2 meters away, you can adjust sizing as you wish, up to 50" large - as big as your TVs.
(Yes, yes, I know: there's a difference in the technology used. However, the first line of the article makes it sound like there is no such thing as a phone with a built-in projector, regardless of how it does it)
