In an open Trusted Desktop Grid system, users can voluntarily participate in order to share resources. Thereby, computational trust is used to isolate malicious agents. Since a fully self-organised solution can suffer in emergent situations like the trust-breakdown scenario, we investigate an additional normative entity to guide the overall system behaviour by still keeping the autonomy of all agents. Within this interactive demonstration, we present a 3D visualisation of the current system status showing how the mutual trust relations between agents and / or groups of agents could be used as basis for automated decisions to issue norms.
