The first update to my third kode80 iPhone app GLSL Studio is now available on the AppStore! This update adds a custom keyboard with arrow keys and coding shortcuts, light/dark syntax themes, code auto-indentation and more. 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.
