I've been fiddling with the LWJGL [1] with a view to making a game for my children. It's slow going because when I learn more about Clojure I end up changing my mind about how I want things structured. OpenGL is all new to me as well - as is game programming in general.
As part of my explorations I came across scratch [2]. It has an interesting approach where every object seems to live in its own thread. That seems to make dealing with state a lot simpler. My initial approaches have been complicated by the fact that the event loop makes handling state kind of disconnected. It would be great to be able to express things in a more linear way. This is what I'm exploring now.
