Electronic Institutions are regulated environments populated by autonomous software agents that perform tasks on behalf of users. 3D Electronic Institutions extend EI with 3D Virtual Worlds, which provide an inmersive user interface so that humans can observe their agents' behaviors. In this manner, they represent a virtual analogy to real institutions. We propose to gain on realism on this analogy by adding intelligent objects to these institutions. Intelligent institutional objects (iObjects) exhibit autonomous and reactive behaviors. Furthermore, they present a limited level of proactivity such as self-configuration. Their inclusion has the advantage of improving the 3D Electronic Institutions architecture and both agent and user interactions within the institution.
