Psychologists and neuroscientists have spent several decades producing theoretical models of the mental processes and neural networks that might  be involved in the kaleidoscopic state of psychosis. Largely concerned with simulating the nuts-and-bolts of the mind and brain, these  computer models generate results that tend only to be of interest to researchers and their scientific colleagues. More recently, scientists have decided to harness the power of virtual reality, in an attempt to move beyond the confines of theory, to simulate the experience of psychosis itself.
