throwing a party next week with a lot of technical and arty folks. I've seen other parties where they had some visualization demos going on a big screen. I've searched youtube in vain for these types of things and come up with nothing. What search term do I need? Can anyone point me at some good visualization demos that I could run on a loop at the party? These will be on an 80" LED bigscreen so they need to be somewhat detailed and have good music with them. any help would be appreciated!
