Each group edited a portion of the wiki, which included both text and embedded Voki talking avatars. There was one wiki for each of my 4 seventh grade class sections. Over a 5 day period, there were 415 revisions from 94 students.
Here is the link to the final revision of their wiki: https://farbercon2012.wikispaces.com/

After the vote we compared the US Constitution with Iceland's new draft of their constitution which, interestingly, begins with the phrase, "We, the people who inhabit Iceland..."
