Handheld projection entertainment has officially arrived. The Optoma and the 3M MPro110 projector are just two of the projectors available on the market.

You’re an online pundit, civil rights activist or budding filmmaker? Get noticed in real life by projecting your portable pitch, plight, or portfolio onto any white surface. My brain is going to explode under the weight of the sheer meta-ness of this. We’re about to see videos of people streaming and screening web videos. Web video can be in elevators, bathrooms and even on ceilings. What’s more, Samsung just announced its AnyCall Show phone complete with an integrated pico projector. It just shipped in Korea.
