What is it?

I'm taking a digital photography class right now at my school. In fact, I'm sitting in that class right now. It's easy enough that I tend to have a lot of free time. Anyway, what I was getting at is that one of our assignments was to take a macro shot of something from an interesting perspective, such that people would have to guess what the subject was. Since I love doing macro photography, I enjoyed this challenge. Here's my result. Can you tell what it is?
