I feel lucky to work on a university campus, because it is generally a progressive environment, a place where art is embraced, and even the common employee gets the chance to enjoy something beautiful and interesting and creative. There are two such projects near the building where I work now (one permanent and the one that will stand for two years).
The first is a sculpture by Deborah Butterfield. It wasn't until I read this article about the sculpture that I realized the statue is made from bronze, not wood. My mind is suitably blown.
The other piece, which will only stand for two years, is entitled "Sidewinder" and was created from black willow and red maple saplings by Patrick Dougherty (with assistance from students in Art & Design and Landscape Architecture). The piece is interactive in that one can walk through the narrow branch corridors.
