Artificial Intelligence

Hello, I am in need of any Artificial Intelligence project that anyone has done before. NLP (using wordnet) would be great A board (not as simple as tic tac toe, could be something like checkers) Eliza implementation would be great Web Agents (crawlers that could grab prices of different product at different links could do) Path Finder (that finds path from a black & white bitmap image) If you have done anything different but falls within the category of Artificial intelligence then please explain to me what is it. You also have to explain me the code. And please make the project is not something already available on the internet. I don't have much time so I am looking for people who have something ready. Forget about copyrights I am just gonna show it to gain some marks and then its all yours. Need it to be in C#.net Anticipating help. Regards, Hira.
