Making an Image Map with Google Images

I recently learned how to make image maps while watching my new obsession, The Google Educast.  Bascially making an image map allows you to take a picture and turn it into a bunch of clickable links depending on where you click.  For example, the picture in the video below has created links such that each person is a link to their Google+ page.

This video shows you step by step how to do this.

How do you think you can use this in your classroom?  Clickable parts of the microscope perhaps?
