CES 2008 was all about HD and the future of televisions. My favorite concept was Panasonic's LifeWall TV, a wall-sized interactive screen that lets each user design their own space with virtual decorations, and screens that follow you and resize depending on where you are in the room. The wall recognizes each indivudidual user, so when the user stands in front of the wall, they have the option to surf the internet, watch movies, display videos or photos, have videophone conversations, and even take remote classes with the help of an IP camera. You have to watch the video to understand how it works, so here it is.
