Which free program would you like made?

Well, I searched for threads like these but I couldn't seem to find any...

I have a whole summer ahead of me and I feel like I should give something to the community (and it definitely needs more freeware), so what free program (reasonable) would you like to see made. I have ~2-3 months to make it, so don't feel shy to ask for something big, just not too big

I will be coding it in C#.

Nice with this sharing stuff. Well since you have 2-3 month I guess to do something big!

I can be with u, I can write c++ program(visual c++)!
