Pythagoras

Pythagoras is a musical sculpture at the Kendall MIT subway station (the others are Kepler and Galileo). It's operated from the platform by passengers waiting for a train. I've always wanted to get a shot of it with a moving train in the background, which is easier said than done without a tripod. Instead, I braced the camera with my neck using the neckstrap and gently squeezed the shutter. Pretty happy with how it turned out!
