I had fun with Photostory. I can see how this would be useful in a classroom setting. Teachers could take pictures of final assessment projects throughout the year and create a looping video to play during the end of year activities. In the library it could be used for the annual Bluebonnet book list. A book cover can appear, followed by a teaser sentence or two about the book. Librarians could use it to introduce the year's new list to the students.
I used Photostory with pictures taken from a DisneyWorld trip a few summers ago. 3 of our 4 sons went, along with my brother's family. What great memories we have - so much so that we went the following summer and took my sister's family too!
