Lightning Creations is an unofficial company that primarily does videogame design. However, by the questions I (Ray Redondo, unofficial founder) post, you wouldn't guess that, since Lightning Creations delves into very different areas of games that few others venture to. One example is creating a software implementation of OpenGL as both a side project and as a foundation for our games that run on older, less capable computers that still have a decently new CPU. Another example is using LLVM to make a game where you need to program a robot and have it fight against another robot made by another human being.
