[lisp-game-dev] Lisp games on Android!

[Simon Ortiz]

I'm thinking that using cl-opengl, rather than making another OpenGL
wrapper, is definitively a good idea. The more standard, the better,
right?

Although I wonder if cl-opengl can be used as is. Android and iOS use
OpenGL ES, which is a subset of the normal OpenGL.

I'll try to adapt cl-opengl into cl-opengles1 on the weekend. Let's
see how far I can go.

I'll let you know.
