One of the virtues of our changing times is that new media has challenged us to rethink and re-examine our basic presumptions about reality and the reality that is virtually perceived. From the perspective of an electronic-media artist, I present bodies of work (CASE STUDIES) of performative-like installations comprised of 3-D structures integrating technology and virtual imagery with the realities of the physical, psychological and cultural perspectives. These interactive installations instigate "social happenings" whereby participants and viewers become subjects from an observational perspective, providing a simulated clinical "case study" in the context of art. Raising issues of belief and perceptions of trust in the constructs of mediated environments, the demarcation between virtual risk and real risk (virtual reality and reality) breaks down.
