Tracery makes graphic input available to web developers. To illustrate some of the ways it might be used, this site presents a "graphical bulletin board"--a place to draw and save graphics, but also a place to comment (verbally and graphically) on graphics already posted.
The image at far left is "hot" - click on it to access an interface through which you can draw or type your response to the graphic. Each image may have an associated comment, so you can offer comments on the image, or modifiy it, or both.
The thumbnails in the lower-left display the "family tree" for this discussion. Click any of the thumbnails to bring it "front and center".
