Broken: Incredible Artworks by Graziano Locatelli. While I wouldn't have considered tiling to be an artistic grid, it is used to great effect in this image. I can't even imagine how the creator was able to break the tiles in such a way as to create the shading and lines to form the figure.
This photo is a grear illustration of bondage because, as you can see, the string around the woman is fairly thin and could be easily broken, therefore, her bondage is an illusion. This concept is best illustrated in the novel when an illusionist "traps" her audience by seemingly making the exits disappear, causing a panic. However, in truth, the viewers were never truly trapped, thus making their bondage only as resticting as they allowed it to be.
