Last night in Santa Monica, CA, from 7pm to about 7am, Glow 08 took over the piers. It was an art and music festival with a bunch of cool events and attractions, but the coolest looks to have been the "Primal Source," a gigantic fountain with projections on it built by Usman Haque. As the video shows, it looks like a gigantic drug-induced hallucination. Which is awesome.
Yeah, what nutbastard said about the drug thing (so I hear). Way beyond this for me though, were fever induced hallucinations that I had once when I was really sick and my temp hit 103+. I was seeeing winged angels and strange creatures and all kinds of stuff that, had I been in my right mind, would have terrified the hell out of me.
