Your browser is slow when applying transform to DOM elements because it has to translate everything 3D in terms of JavaScript and DOM. If you want to manipulate images and elements effectively in 3D then you have to learn matrix computations, quaternions and stuff which is horrible for the common web developer. I'm saying that if you offer a new approach that could mix HTML/CSS and encapsulate those complex 3D concepts it would be interesting.

I'm assuming this is not in the right place because I don't understand how it answers my question.
