smartphones seem to be able to do almost everything these days. but can they do this? >> there is a display of 10,000 iphone 5s just lined up in a domino setup. >> ah! >> it's working! >> they make an elaborate curly q pattern, it's tipping over. >> when it goes into the elevator, the elevator goes up, and it keeps going to the next floor. >> which brought the trick up just a notch. it wasn't just one floor. it was two floors now. >> then it finally resolves with this big kind of mural of iphones. >> so is this the real domino effect, or domino special effect?
