High-LowTech has developed a new kind of wallpaper that is incredibly tech-savvy and user-friendly. The 'Living Wall' has lamps and messaging capabilities installed into it.
The Living Wall can send messages to people in other rooms simply by swiping the wall. I don't exactly know how that works, but it sounds cool as hell. The best parts about the Living Wall are its lamps. Touching the wall turns on and off the lamps, allowing for an intuitive wallpaper experience.
Living Wall is still just an art exhibit, but it may see release someday. Your interior designer won't know what hit him.
