Flash Replacement

Flash is obviously dead/dying, but I still want to be able to write online games (complete with vector animations and all). I've been studying Javascript, SVG, and some neat stuff with HTML 5. However, I've found very little in terms of a platform to tie it all together. What do you recommend?

Desired features:
* Free as in beer
* Helps with image/sound resource loading
* Helps control animation in a standard way

Box2D comes surprisingly close except for the resource loading. But it would be pretty hacky to have all screens as 2d physics environments.

GNU is designed for its own sake, not for Windows. Its foremost philosophy is to be useful for anybody. If it performs better for a given metric, that's a bonus, not a main goal.

Do you think the Adobe code base is any lighter? I'd doubt it. Configure is terrible because it solves a very tricky problem of building on any Unix system. If you only had to work with GNU, it'd be much lighter. Why do you bitch about comments when it has no bearing on the final work? It's no longer 1980, we can afford the disk space for commentary art.
