Tunnel of Light and Sound

Today I was in Detroit, and the airport here has an underground walking tunnel between terminals, very similar to Chicago O'Hare's.  While O'Hare's is somewhat tacky, Detroit's is more modern.  It has moving walkways on each side with a wide aisle down the middle, but the interesting part is the lighting walls which change color periodically all while this eerie music plays.  It's weird, but I like it.  It certainly makes the long walk through the tunnel less boring.  More photos of it are shown here, and more info on it can be found here.
