Josh Azzarella is a video artist I learned about recently, who takes famous scenes from history, the cinema, and other sources and removes central points of action. Supposedly, he uses photoshop and/or after effects to do these things. I was moved by this one in particular, and found it quite odd and even funny. Definitely one of my new favorite artists.
This one is called "Untitled #27 (Unknown Rebel)," 2006
