    I will, thank you!

    Yes, it does resemble what I'm seeing, as far as the movement of the light pattern. I am hoping to prove it out further, if we can set everything up again and "recreate" it by having someone walk through and compare any differences.

    Thank you for pointing me to the video, I had been looking for one that showed what a person would look like moving through the grid.

    Any grid projection would work ... a bright light in a box and a grid with holes!
