Convex Concave Rocks optical Illusion
Convex Concave Rocks optical Illusion is a snap shot taken Wild Horse Canyon in Utah. Mandy pointed out that both of these images are identical just the bottom is flipped upside down. The top picture appears to be a normal rocky hillside with concave holes in the facade, however the bottom picture appears to have strange convex budges coming out of the side of the mountain. Its amazing how much the shading of the shadows can play tricks on our eyes.
That is pretty cool.
