Three.js editor
I fear that three.js will be more or less obsolete with the rise of emscripten/asm.js which allows basically any 3D Engine there is to Run inside the browser.
There is still some work todo in regards to quicker deployment but i wouldnt invest heavily in pure JS based engines right now as there will be tremendous leaps in this space (eg Unreal Engine3) in the coming months.<p>That being said, this is an awesome Tool!
