>I still have no idea what this is supposed to demonstrate.

Did you add a character and animate it? Did you try making a soundtrack?

Are all the features available on IE? How do the framerates compare to other browsers?

Try going to "Scene" and uncommenting the line that adds shadowBlur = 10;

What happens to the framerates?

I'm guessing the app doesn't work one bit on IE8, which looks like is still the most popular version out there.

Of course, if you install Chrome it stays up to date automatically. None of that IE7, 8, 9, 10 crap.

Did I mention it's also the world's most popular web browser?

And it goes without saying IE is non-existent in the mobile space.

How many features of the moviemaker.htm work on a mobile IE?

They all work (even the Web Audio API parts) on an iOS 6.
