yall DO realize that this was made in cool edit or sound forge or something similar (fruity loops even), and the audio was exported, and the visuals were made in Adobe After Effects... I'm willing to bet 96% there's no way this could be mixed that precisely, the audio exported AND the motion being captured (it supposedly was done on windows 95 or 98 because the sound recorder is called sndrecord32.exe.... that hasn't been the name in a while...). I'm sure most of us realize that, it's just that on the page the file was hosted, there were alot of people that believed this was made live.
It doesn't matter anyway... the guy still has too much time on his hands. Give ME some.
