From your API document, there is a sandbox we can try to draw something. But the page is gone.
Hi Devon! Plenty of time has passed since then, but sandbox is now back online: http://animatron.github.io/player/sandbox/sandbox.html
It takes longer as expected, unfortunately — but this way, seems, you will be the first one to try it in action in a new state.
The sandbox was disabled due to massive changes in API, I think now API is stabilized and it's quite safe and easy to turn it back on — so I will do it in a day or two and notify you here, please stay tuned.
