Are you a developer who would love to get into video games but get scared when he hears "OpenGL" or "rendering engines"? Or Maybe, you never considered writing a video game because you have heard Ruby was slow and you are not ready to give up on your favorite programming language. This talk is for you then. Together, we will build a very simple game using Ruby and the development tools offered by Apple. At the end of the presentation you will be ready to get started on your own project.
