This is a very old AMV I found on Kazaa years ago.  
It's nicely done, but has tons of gore so if you're not into these things you'd better pass. :P
Footage includes Ghost in the Shell, Perfect Blue, Evangelion, Akira, Ninja Scroll, Vampire Wars, X, Wicked City, Jin Roh, Ninja Resurrection, KITE, Spawn.
Thanks to budtowery2, Xanax11 and WierdestBudday for pointing out some of those.
Sorry I've missed them, I haven't seen all the anime that were used in this clip. At the time I downloaded it, I was more into Korn rather than into anime. Things have changed in the last years, however.:P
