This is on display at the Atlanta Airport along with other similarly themed pieces.
The colors... I've enhanced them. I'm sorry. My photo was a bit dull.
The piece is interesting in real life.
If you're ever in the ATL airport and are not in a hurry, don't ride the train, take the moving sidewalks between concourses and see the sights!
(... and maybe get some exercise along with it.)
Is this the tunnel between the terminals in the Atlanta airport? I has a long layover one time and walked between terminals. I was glad I did. A very cool collection.
