The Storytellr authoring tool generates multimedia stories from user-provided sources. Stories are written in grin and presented as multimedia movies played on a story canvas.
The intended audience is lightly-technical, and / or end-user technical. The end users may be familiar with how to use a computer, but are unaware and indifferent to technologies like Java, XML, and SMIL. The users are only casually interested in storytelling and do not have enough interest in learning (or acquiring) authoring tools such as PowerPoint, iMovie, or Adobe Premiere.
An example story is shown below:
The Storytellr compiler was written in Java using a Flash library to translate the stories for presentation on the web. Storytellr also supports SMIL, a multimedia XML language. The web application is written in PHP.
