Thanks!
@Kirl: 2.5D matte painting looks really interesting, never heard of it before.
I found JS really easy to get, it helps that I've been coding on other languages for some time of course.
WebGL is Opengl ES 2.0 and I've done some of it on my experiments on Android, it was also really nice to code.
@boogop: I've checked webgl before (some years ago), but didn't have enough experience on opengl to fully understand it, also never liked html, always thought it was slow and incompatibly.
Now seems to be a standard that those browsers companies agree to follow (IMHO).
