I hope that this hasn't already been posted. Richard Feynman's Airstream Interplanetary Explorer was recently displayed at Fermi National Accelerator Laboratory in Batavia, IL. It wasn't mounted on the big pole, just parked on the ground. I won't comment on the "art," but I did think the trailer was pretty cool.
Here are some pics of the piece when it was first unveiled:

I took some pics of the Interplanetary Explorer that show the interior in some detail. It is essentially stripped to bare metal. It also is filled with metal supports to hold it all together when it is lofted into the air. It is definitely NOT towable in it's current condition (unless it is on a flatbed).
