iTunes 8.0 Visualizer is simply a Beauty!
Now, I also wanted to say congrats to Robert Hodgin in case he is reading this forum, because he is the one who developed the visualizer before Apple bought/got it from him, if I am correctly informed here. I had an older version of his visualizer before iTunes 8.0 and thought it was great, but this version is twice as stunning
