appCobra is a visual programing environement that generates pure HTLM5 so you run it in every modern browser. I got the trial but so far I didn't have any time to test it.
It looks very easy to create animated content, you don't need to code anything. However you have to upload your app to their server.

If you visit their website and see "take a tour" you will have a better idea of what it is.
