This is a quick little video that shows how the sets are built in order to trick your eye. By building these on an angle your mind wants the body to align towhat it knows is correct.

I tried to go through the mystery house but it triggered a vertigo attack that about dropped me to my knees.

As I showed before two pictures of Miss Lynn. Both shot from the same spot with the same camera settings.

The imae on the left looks larger. While my splice is not perfect youcan plainly see that by drawing horizontal lines from Lynn to Lynn you can see they are the same size but the way it is framed by the Structure beyond.

Simple but effective illusion.
