The Literacy Shed has a wealth of visual resources to use.  The curator has tons ( and I do mean tons) of short animations to use for lessons.  He also has lesson ideas to go with the animations.  The animations themselves are beautiful and I think there is a lot of potential for creative writing.
The site has many sheds with different genres of images and animations as well as teaching ideas for each of the areas. Here is an example from the Fantasy Shed.  Scroll down to "Once in a lifetime"  to view some gorgeous animation that students could write narration for. 

The images are ultra engaging!

Today I made my first  Blabberize.  It was relatively painless, but not exactly as easy as I thought it would be.  After downloading an image, I had to find a microphone that hooked up to my new computer. I don't imagine this would be an issue on a Mac, but I use a PC desktop at home that did not have an embedded microphone.  Then I had to figure out how to record the sound ( again I think this is a PC issue) Finally I had to convert the file I made (WMA) into an MP3.  I had to download a converter to do this.  Once I had everything I needed, it was really easy.   I think kids could have a blast with this.  Think how if fun it could be to have an animated picture deliver your presentation.  It would enhance script writing as well.
