I went to my photo archives and found shota I thought would work for both themes: Show Some Circles and Model.
I decided to use shots from the Nature Research Center (NRC) in Raleigh, NC. The NRC has many circles as well as models.
The NRC is a relatively new 80,000 square foot wing of the NC Museum of Natural Sciences. The goal of the NRC is to bring research scientists and their work into the public eye, help demystify what can be an intimidating field of study, better prepare science educators and students, and inspire a new generation of young scientists.
