About the Authors

Peter Boerboom and Tim Proetel both studied at the Academy of Fine Arts in Munich between 1991 and 1998 under renowned painter and teacher Horst Sauerbruch. Their long friendship has repeatedly led to joint work. This book is the latest result of their collaboration, which included many drawings and discussions. Three volumes about perspective, light, and motion are already published; more volumes on new themes are being planned.

Tim Proetel is an advisor for art at the state institution of school quality and educational research and teaches art and theater at an academic high school, both in Munich.

Peter Boerboom also studied communications design at the College for Design in Munich. He is a founding member of the artist group Department for Public Appearance and executes art and photography projects together with Carola Vogt.
