How should I design a visual aid presenting the theme and symbols of Macbeth? What images should I include? Why?

I would try to find images or icons that would represent
characters or specific relationships in the book.  For example what symbols or objects
could be used to represent Macbeth, Lady Macbeth, the Witches? Trying to find these
images and then being able to explain how they connect the characters can help display
your understanding of them and allow you to post on a visual what you believe.  What
object or symbol could be used to describe the relationship between Lady Macbeth and her
husband?  Could there be objects used to describe their relationship at the start of the
play and then at the end of it?  What object could be used to represent Macbeth's
beliefs in his soliloquy, "Tomorrow creeps in this petty pace"?  These might help you
get a start on this task.
