This was my first ever C++ project built with Qt back in roughly 2010. It was a pipeline tool to help with debugging and to sequentially render any arbitrary number of .ass files. It would let you dynamically load in objects to render. If you are curious about the naming convention, Arnold (named after the man, the myth, the legend). The binary that renders is named kick, and the files it renders are .ass files. Hence the name Kick Ass GUI.
