My third kode80 iPhone app GLSL Studio is now available on the AppStore! GLSL Studio is the first fully featured OpenGL programming environment for iOS enabling graphics/game developers to work on GPU code and effects directly on their iOS devices while also providing a safe and easy environment for aspiring developers to learn through experimentation. GLSL, OpenGL Shader Language, is a GPU programming language used by most modern portable devices and new technologies such as WebGL.
