I recently came across with Storybird which is basically a website that allows you to create stories digitally based on a series of pictures you can choose from. Then you can add each picture to a different page, as in a real book, and star writing your own story. (http://storybird.com/)
Storybird has been identified as a fun collaborative storytelling website since it offers the opportunity for several people to work on the creation of one story. This is why this tool is perfect to work in classrooms.
The website has been working for a couple of years and nowadays more and more websites dedicated to the creation of original stories have been developed and received successfully. Xtranormal is a great example of the possibilities you can have when using technology for storytelling. (http://www.xtranormal.com/)
Now it is easier than ever to tell stories with high quality presentation and both, kids and adults, can do it. Having the access to these great tools have changed the way people tell stories. Storytelling has as well became a more collaborative process.
