For my art history class we had to go to the Philadelphia Museum of Art and I saw this amazing installation by Carlos Amorales. It's called Black Cloud, and although it makes me itch a little, I think it's really beautiful. Each moth is cut from black paper and strategically placed to give the feel of a plague. What I really loved is when you left the main room and walked into other rooms throughout the museum, you would see a small cluster of moths linking you back to the installation.
