Am a long time practitioner of industrial simulation for problem solving, so this intrigued me. Can we more effectively use VR to model worlds that represent our own? And can that can be used to test design alternatives? Does this only work in spaces that drirectly map to our own, like 3D flight simulation?. When the worlds are more abstract, the case is not so clear. See below for video demo.
