Hi!
Just wanted to show you a new game in development using cocos2d and 3D OpenGL mixed together.
Cocos2D is used for the menu and in game icons/labels either at static position or computed from the 3D world.
(e.g. damage counter for crashed cars).
Mixing cocos2d and opengl 3D stuff is quite easy indeed.

Btw, what do you think about this game in general?
If anyone ever needs help integrating 3D into their cocos2d game feel free to contact me.
