play a tune when kicked, sure, and we're pumped to see the World Cup in 3D, but it's not often that someone comes up with a serious technological makeover for the sport that's nearly as old as life itself. CTRUS, however, is just that -- a theoretical revolution in soccer that begins with the all-important ball. To start with, a reinforced elastic structure means that CTRUS doesn't require any air. (So long, pump.) Next, GPS and RFID chips keep track of the ball's position at all times, and tell it to light up in different colors when it scores a goal or is accomplice to a nefarious violation. (Farewell, referee.) Last but not least, the sphere itself will report back with accelerometers that measure the ball's kick force and travel speed, and a camera that could (with magical software stabilization, of course) actually film action from the ball's own POV. Sadly, the ball is just a concept from an undercover marketing agency, but since we're dreaming, we urge its creators to add a second camera. Just imagine just how immersive it would be to have your face booted in at 130km/h in glorious 3D. Or, just peek the concept videos after the break.
