Here's one of those "this is the world we live in now" stories. A few days ago there was this video making the rounds online that appeared to show some guys in Times Square taking control of all the video screens in the area - big ones, small ones, screens all over - using only an iPhone and a little electronic gizmo plugged into the top. They would walk up to the screen, press something on the phone, and then they'd be on that screen. It got picked up on tech blogs as this amazing new technology. Turns out everyone was fooled (except me! I knew it was fishy!) and it was part of a marketing campaign for the new Bradley Cooper movie Limitless about a guy who suddenly gets the ability to use 100% of his brain instead of 10%. The New York Times reports that the people who made it aren't even all that experienced at advertising, they just had an idea that worked and filmed it on a shoestring.
