Pictures used in Picturing Programs

The following are some of the pictures I use in my textbook. I've included only the ones that would be impractical for you to build yourself: I haven't posted a picture of a solid green rectangle, for example, nor anything whose construction is a homework problem. As far as I know, all of these pictures are in the public domain.
