Sweet Site

This site is actually really neat, they have free poses to draw of people in dynamic poses. I even noticed that they rotate to get different angles, though I don't know if all the images do this.

Found Drawings Discussion

The definition of drawing that we came up with was a moving point. Moving points create lines and a drawing is made up of a multiple variety of lines. An excellent drawing would have texture, a variety of line weight, an interesting composition, and an interesting use of space. When people in the group were taking pictures of found drawings, they looked for pattern, repetition and an interesting line quality. With this criteria, we picked the images that conformed to these ideas the closest.
