i wish my cell phone had a built-in beamer. imagine what you can do with that! (apart for businessmen playing their sales pitch.) i’d like to beam on the ceiling of a train for example. just cool clips warning young adults for old sex crazed men. you could use the rear window of your car for beautiful cityscapes. or project the milky way on any surface of the earth. why didn’t anyone invent this yet? please big heartless corporations, make me a happy consumer again.
