What are some good beginner programmes I could write to practice?

Question

Hey guys,

Just wondering if you have any ideas for programs I could attempt to write? I am begginning C#.Net and I am currently trying to write a HangMan game. What are some other things I could attempt to write?

I just need ideas as the only other things I have thought to do are things like adding numbers together when they are entered into a box etc. The hangman game is my only half decent idea so far for a program that will actually do something and help me to learn.

Cheers guys!
Dan
