Lenticle printing and Light source as an indicater

Saw this fence while out on a walk. Reminded me of  lenticle printing. One thing struck me tho about this. I was able to move so that when i looked at the fence all i could see was the lit up parts. Then when i changed my possition and walked along the fenced i was able to note that the lite parts of the fence grew smaller as the light source got further away . This reminded me of the line of sight and explains why in my lenticle printing a certain amount of distortion took place.  Note to self : Use a light source to indicate the viewers perspective.

For example here is the diminishing line of sight as illustrated by the light.
