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.
