We used this to turn Monster Island into an IPOD zombie novel - ( checkout the download page for a zombie parody of the IPOD ads)

but we removed the navigational elements inside each note - turns out if you leave the nav elements off it's actually easier to read, and the IPOD bookmarks the last page you read. With naviagation elemtns ou have to scoll all the way through the book to extit - which is a pain, so we just dropped them
