The Exquisite Forest is a very unique project that’s sponsored by Google and The Tate Museum of Art. Users can collaboratively create animations. You can learn more about it in this video and also be reading Richard Bryne’s blog.
The exhibition at the Tate which this online project is connected to is only supposed to last six months. So, until I learn that the online collaborative aspect is projected to last longer (and I’d appreciate it if anyone knew about those plans), I won’t add this to The Best Ways For Students To Create Online Animations.
