Chicago O'Hare

I almost never fly United, so when I had a two hour layover at Chicago's O'Hare airport, I wasted no time in heading over to the tunnel between United's B and C concourse in Terminal 1. The tunnel, designed by Helmut Jahn is home to a light installation by Michael Hayden titled 'Sky's the Limit.' The installation is coupled with moving walkways and ethereal music that synchronizes with the lights. If you listen carefully, you can make out Gershwin's Rhapsody in Blue, a nod to the long standing usage of the tune across United's media.
