Sand art tends to be a dime a dozen because of the unlimited amount of material around to be used, but making a sand optical illusion is no joke. These mind-bending illusions were created by Jamie Harkins, who is not only a talented artist, but a skilled illusionist.
Looking at these illusions, it would be impossible to make anything out if you were just looking at it on the beach. When you take a look from overhead, you see that these lines all come together to make something truly head-scratching.
The images are all 3D in nature, but as we all know, they're simply lines on the beach: a fun, but fleeting piece of art.
