Isabelle Jenniches, Stefan Kunzmann and Renée Copraij presented a short performance in spring 2001, in the historical anatomical theatre in De Waag in Amsterdam. This was once the ‘hometheatre’ of anatomist Nicolaes Tulp, ‘surgeon and representative of the civil authority, anatomist and frequent office holder in the bourgeois government,’ to quote Francis Barker (1995, p. 103). Tulp is the man depicted by Rembrandt in his famous The Anatomy Lesson of Dr Nicolaes Tulp, which shows Tulp's magisterial dissection of the executed criminal Aris Kindt :

Jenniches, Kunzmann and Copraij chose this theatre for a performance in which they engage with the Cartesian mind-body opposition, and the identification of mind with that which does the thinking.

One day prior to the performance, the audience received an e-mail with an invitation to visit the project website, http://www.9nerds.com/sk/waag/. Here, the audience encountered: a) a figure consisting of several lines and several small circles ‘dancing’ rhythmically up and down; and b) a discontinuous line, moving in the same rhythm. The visitor was given no clue as to the purpose or intention of this figure. The only way to try to understand it was to engage with it, and to engage with it meant to move through it. After clicking on the image, the visitor was able to move the discontinuous line through the figure. When this line hit one of the small circles, the appearance of a little hand sign invited the visitor to click again. As a result, a connection between two little circles was made, and the line in the diagram connecting these two little circles would become slightly thicker. After clicking, several of the circles would disappear and/or others appear, allowing for new connections to be made.
