New gadgets! Samsung unveiled its new Galaxy S4, in the form of a Broadway-esque show. The new phone has eye-tracking capabilities, gesture control, a 5-inch HD screen, and a rear-facing camera. These features were demonstrated by a bizarre set of performances, ranging from a tap-dancing kid to a bored housewife. "We have taken technology and innovation further to help us get closer to what matters in life," Samsung executive JK Shin said on stage.
