In this paper we describe an application model for a collaborative narrative in a multimodal tangible user interface. We investigate how a story can be developed in negotiation between three users. By collaborating the users create a soundtrack and negotiate the next video sequence. We developed rhetorical principles for editing moving image material for a node based interactive system. We present a new concept of quality in the user experience that we define as ambiguity, user experience caused by the tension between complexity, control and risk.
