I understand that everybody already knows about this form of art, but i still find the complexity of the illusion astounding. I am talking about sidewalk art. This link (http://www.huffingtonpost.com/2010/03/01/3d-sidwalk-art-that-will_n_478649.html#s71257&title=Rocky_Road) includes 20 separate pictures of this style of artwork. The artists play with our perception as the obviously two dimensional sidewalk suddenly starts to pop out with a three dimensional image. The images range from elaborate murals to over sized soda bottles. To create these the artist plays with our monocular cues. We know many things from everyday life, such as more distant objects seem smaller, and darker spots are shaded from the light source. Binocular cues are useless because the image is two dimensional in reality.

Very cool stuff. I think it would be really difficult to create these types of artwork!
These never get old. Even after learning about how the artist manipulates us to experience the illusion, my mind is still blown.
I always loved these types of illusions, but now that we have learned about their types and underpinnings it find it to be even more interesting.
I really like those 3-D sidewalk Arts you show here. They are fantastic! These artworks are really good examples to show how our perception can be tricked, particularly vision. I think it is important for us to learn about the biological basis of perception, which can help us understand our limits and our strength making sense of the world.
