Just found this application through Google.
Great I was up and running with this very quickly. Shame I couldn't save but then I guess its only the demo. So easy to use. I liked that fact that I could create clip and frames, makes it easier to keep different actions together. Wow, to draw graphics on top of the animation as well as create a drawn animation in its own right, I can really see potential in this. Great that I can select the items I have drawn and move them and size them, just like a drawing package, and they are not bit maps! (No loss of quality when I resize)

Adding a background allowed me to put pictures behind my little drawn animation, really cool. Can't test the chromakey as I don't have one yet. Like the onion skinning on single and mutliple frames.

Just found the time lapse.
GREAT APP!
