I wish there was a loop funtion on flash...
I like the pulsating graphics and I gotta admit that I can't see any flaw, at all. Maybe the audio was a bit shabby, try better quality. But the style variation and idea rocks my world. Maybe you could have add some more movement for the "mad man" and maybe some more people involved. But I bet you sought simplicity...
I can't see anything that may hinder your work for the fans. Gotta say I'm almost one of them. Keep up the work!!!
