I'm sure yiz all know me here (or at least most of yiz).
Anyway, I'm not half-shabby at writing C++ programs that are multi-threaded and cross-platform.
For my final year college project I need to come up with something new. (They won't accept Dynamo since it's already been completed).
Please suggest something that will be very useful and will be used by thousands of users (both Linux, Windows, and Mac). It need not be directly related to networking, any program at all that people will find uselful.
It will be free and open source.
