In this paper we present a software environment for visualization and interaction on the Responsive Workbench (RWB). Our main focus will be on the RWB Simulator. We will also briefly describe the architecture and the usage of the RWB Library. The RWB Simulator is an excellent tool for development, evaluation and analysis of the RWB applications. It is a powerful introduction, learning and presentation tool for the RWB. We will also present a novel method for development of immersive VR applications. Finally we will demonstrate the RWB Simulator on some visualization applications.
