Been playing with Shadow Puppet as more than just short commentary on photos. I re-did my design safari photos as a Shadow Puppet story. I had some issues uploaded the larger file but Carl now has released a new version of the software that allowed me to create, upload and embed the story easily. 

It is a really elegant and useful solution to putting audio and photos together – can be used to create educational presentations very easily now that the 4 minute upload limit is no longer a problem.
