This is a great install we did for a customer in Austin, TX.  We used a dual arm articulating wall mount to allow for the mount to moved around for adjustable viewing angles.  This way the customer can watch the 60in Sharp LCD  from the couch or from the kitchen.  Below the LCd we installed a shelf with a ipod dock and sound bar.  We wired this into the tv allowing for audio to come from the tv or ipod.  All the wiring was hidden inside the wall for a very clean look.
