Personally I think that VJ-ing is all about human intuition and carefully listening to the music. It's tricky to improvise and find visuals that match the given mood, layer realtime NestDrop visuals and pre-rendered visuals together, all while trying to keep things fresh and alive. I don't think it's a skill that can be automated with the same level that a person can pull off. NestDrop just creates visuals which respond to the beat, it's just one piece of the puzzle... Not an utter solution.

ok, but you can use this prog like anything else, make it your way.
