Check out this Wall of Sound. If you use a magnifying glass on the bottom right corner, you can see the iPod.

That’s right, this is an iPod dock to end all iPod Docks. It is spiffy 3×4 foot frame that weighs about 225 pounds, capable of putting out 125 watts of pure 40 Hz-20 kHz frequency response sound. It is quite expensive at $4,500.
