Virtual Hallucinations appears to be quite an interesting and eerie project. Nash Baldwin, a medical doctor who also has a decree on computer science, created a virtual reality application that mimics the sensory experiments of actual schizophrenia patients. According to the article, cheerful, repeating voices and intrusive environment are haunting. I think the fact that the visitors know it's an actual perception of a mental patient may have a multiplying effect on the world. Although this may seem a bit callous, I thought this kind of knowledge could be useful in creating a very interesting computer game.
According to a BBC news article, virtual hallucinations seem to have a good effect on actual schizophrenia patients. For some morbid reason, the experiences of mental patients are quite intriguing to me. For example, Spider by David Cronenberg appeared to me very insightful.
