The wall gives notification and instructions and allows the user to interact with the display, while not committing to involvement. As the user approaches the wall in this phase the previously drawn images gradually fade to white.

The kiosks show images that people have previously taken of the wall. This both clues people in to the fact that you can take screen shots of the wall and allows new users to view drawings without being committed to interacting with the wall.

For a $1 donation, users can email or print out images of the wall.
