Anatomy Pinball

Studying for the MCAT? Take a break by playing anatomy pinball! Created by  Canadian visual artist Howie Tsui, it's called "Musketball!" (2012), and is 1 out of 3 pieces - all part of the "Friendly Fire" exhibit. The message is that repetition can desensitize one to war. A heavy message, but a gorgeous piece of work. Which organs are missing?
