I just discovered MovieStorm, free software for Mac or Windows that allows users to create animated movies. The software download is quite large (in total, almost 500 MB), so if you are trying this, be sure to use a solid, high-speed connection.
While I have not had a chance to dive deep into this tool, it seems fairly easy-to-use and has enough potential to keep more advanced users engaged. The tool could be used as intended for creating and narrating movies, and then sharing with a wider audience. Or, the program could also be used to plan, storyboard, or sketch ‘real-life’ video projects, including set design, lighting, camera angles, and script. While the tool is free, there are content packs that can be purchased.
I am not sure how long this tool has been around, or if there has been much work done with it in classrooms, but I am excited by the possibilities for movie production and storytelling.
