This is a remake of my old work you may find in Scraps. There were many "shadow" spots on the wall, and I finally fixed it. Also I changed colors and put a HIDDEN TEXT on the wall, can you read it?
This stereogram made from my 2D photograph of the monument in Washington DC. I used Stereogram Lab software. Tile and Depth Map made in Photoshop.
