The tour guides took a computer backed camera with a program that converts a human form into stick figures. So a energy walking would appear as a stick figure walking.
As they witnessed a stick figure climbing a wall, one of the guides was taking pictures from behind the video camera position.
They show shadows climbing the wall, in sink with the computer generated stick figure.
They are trying to split screen, to show the evidence. Then we will share it.
This is creepy. Of course guides being fearless thought it was great!
Go figure.
