I opened up a folder and was instantly disoriented by this photograph. I wasn’t even sure for a while which end was up but I think this is right:
It’s the east stair tower of Anderson Biology, looking straight up. The aluminum tubes arranged in a circle are part of what was an enormous, intricate floor-to-ceiling mobile by Rice art professor David Parsons, which has been gone for quite some time now. There were originally two, both installed outside in the elements. The other one was in a Geology stair tower and was destroyed by, I believe, Hurricane Carla. It was amazing that this one stood as long as it did.
Bonus: In the east tower of Anderson Biology, a ghost.
