Modus Museum offers an interactive and collaborative museum space for the artists and the visitors. In order to engage the visitor with the site, a cookbook is given to the visitor. The cookbook comprises of the tools, the materials available on the site and the possible atelier infills applied on the prosthesis. So the cookbook is not an instruction book, but a booklet that opens up to different possibilities and answers different demands of the users. The user is free to make customized interventions with the available materials.
