When I built my house 6 years ago I designed the built in cabinets to hold a standard TV. The cavity is 52" high by 38.5 wide. I would like to find a mount that stores a wide screen TV in this cavity when not in use. When in use, the mount would need to move the TV forward (enough to clear the cabinet), and then rotate the screen 180 degrees for viewing. Any suggestions? This will probably cost as much as the TV, but the cool factor may be worth it to me.
