AFN to AFD is one of my very first programs written in C (in 2005). I just came across it as I was cleaning up one of my old project folders. The main objective of the program is to convert a non-deterministic finite automata (AFN) into a deterministic finite automata (AFD) and to display, using C style graphics, the two types of automata. Here are two screenshots (in the left one, we have the AFN and in the other one, the resulting AFD):
