My current code is pretty trivial; dropping in a pair of standard shaders and tweaking the code would probably be sufficient.
WebGL is interesting, but it only just got support in IE11 [1]. My only current project with a web requirement would need to support older browsers, including older mobile browsers, and Safari and Android browsers also lack support.

Depending on how difficult it is. Might be an interesting way to bring codebases that target OpenGL ES 1 onto WebGL
