I have visited Gunther von Hagens' Body Worlds twice. Once in the Beurs van Berlage in Amsterdam, years ago, and once in Rotterdam. At this moment it's in Amsterdam again. Surreal and a playground for medical students.
10 years ago Gunther von Hagens started The Plastinarium in Guben, Germany. Here, 40 different scientists are performing the art of plastination. Creepy and beautiful and intriguing at the same time.
