This one reminds me of a badminton birdie. By the way, the building in the background is the library. The stacks there were done by Louis Comfort Tiffany and they're spectacular. They're made of glass block so the sun shines through the floors and the rest is intricate metal scrollwork. (I couldn't take pics inside without a student ID, or I'd have shown you.)
I especially like the texture on this one.
This one is really quite haunting.
And this is my favorite. The base is left mostly natural.
This one is missing its plaque, so I don't know who the artist is or anything about the piece. I almost didn't post it without being able to give the attribute, but I liked it, so it's in. If anyone knows anything about it, please let me know and I'll update this with proper attributes.
This is another of my favorites. It looks like it's about to go off or something.
