I had to stop watching about half way through. Very cool and creative but at the same time disturbing.
That's fucking nuts man! Nice find! Plus rep for sharing! I cant even begin to imagine how long that took him.
I saw this video a little while back, but i only saw it from the part when he crawls out of the crack and onto the walls inside the building. I never knew there was that entire part before hand. Definitely an amazing video.
This has been posted before, there's a few others by the same artist that are just as amazing/disturbing
