On the list of things that would freak you out if you came across it in the middle of the night you would probably crap your pants, Clement Briend has his own spot. In fact, if he teamed up with the creepy tree guy, and had that tree on a hill, and projected one of the faces onto another tree on the side of a road, I would be freaked out.
However, I wouldn’t be against trying this myself somewhere on an old dirt road somewhere in the middle of nowhere. I’d have a spy camera set up though to capture reactions. Maybe even have it automatically turn off right after someone saw it. Yea, that’d be awesome.
