Check out the artwork for Rosencrantz & Guildenstern Are Dead! I am particularly proud of this one. Even though I did not do any of the design whatsoever, I did suggest to Patrick the idea for the coin.
At the start of the play, Rosencrantz is tossing a coin up in the air over and over again, and every time the coin lands heads up. I thought this would be a cool starting place for the design image ... and now here you go!
