Dan Iverson and his wife strapped a GoPro video camera to their son's head, then played hide and seek with him. It was the boy's turn to seek. In this point-of-view video, you can almost see how the child is trying to reason about the possible hiding spots.
During the entire hunt, the parents are hiding in a closet, watching a live feed of the video on a cellphone. They might still be there now if Ollie the dog hadn't helped the boy.
