Wall Mount: Samsung WMN-5090
Samsung's WMN-5090 wall mount uses motors for tilting and swivelling, and it connects to your television's RS-232 port so that you can adjust the screen's movements via on-screen controls. It can store three positions in its memory, too, which means that you can program it with one setting for when you're watching from the couch, another for when you're watching from the kitchen, and another for when you just want to discourage other people from watching it, for example. The wall mount automatically senses where the wall is to prevent the set from crashing into it.
Unfortunately, this particular model works only with 40- to 52-inch Samsung plasma and LCD sets that are equipped with an EX-Link connection, and it costs about US$800. But it'll wow your guests and scare your cat.
