Here is a demo of porting glxgears to the web: http://ehsanakhgari.org/blog/2012-01-25/porting-opengl-application-web
So far I can't find any OpenGL ES 2.0 games. Most FOSS games use OpenGL, not OpenGL ES. And the few that do use OpenGL ES use OpenGL ES 1.0 or 1.1, which is very different than 2.0 (2.0 is parallel to WebGL, 1.0 and 1.1 are not). Any help in finding an OpenGL ES 2.0 game would be much appreciated! It would be a nice way for us to test our compiler, and it would give the game a new audience on the web
