Having a hard time tracking the family at dinner time? Microsoft Research is working on a clock inspired by Harry Potter movies. The Weasleys' home has a clock that tracks the the whereabouts of each family member, so Microsoft wanted to reproduce the effect by building a very similar one. Apparently, the clock has "small photos of each family member's head that float from section to section depending on their location." The clock recieves text messages of their location and updates it in real time. The concept is expected to be available in two to three years.
