Now WebGL works in almost any browser, including mobile ones so it was tempting to try it out. We have experience in creating Android apps using OpenGL ES 2.0. We have released quite a lot of 3D live wallpapers with rich 3D graphics. They are implemented in Java + OpenGL ES 2.0 without using third-party game engines (such as Unity) or high-level frameworks (such as libGDX). This makes our apps lightweight and well-optimized. And since WebGL is based on OpenGL ES 2.0 process of porting live wallpaper to run in browser is quite straightforward.
