In this presentation, Birgitta Hosea talks about the collaboration between herself, Maryclare Foá, Jane Grisewood and Carali McCall that resulted in the book Performance Drawing: New Practices Since 1945 (Bloomsbury, 2000).

Using material from chapter 3, in itself a collaboration between herself and Foá, she considers the score as a form with which to invite participation and unexpected results when working with others. The presentation concludes with an overview of a participatory project in live animation.
