suggestions for first moderately ambitious application?

Hi, everybody. I've been studying C# (using Visual C# 2008 Express) for several months and I think I've got the basics down pretty well at this point, so now I want to create a moderately ambitious application to consolidate and grow my skills. Any suggestions for what kind of app would utilize the full set of skills that would be expected from a preprofessional level student?

I posted this message to another user about a Uni Project...

"How about something slightly different.... Maybe a remote drawing application? (Like instant message drawing) that works over a TCP or UDP connection and supports basic shape drawing + encrypted transmission.

Then you get some connection based stuff, some graphics and shapes fit quite nicely with polymorphism normally so would be quite nice all around."

For the drawing you could also store a database of actions (allowing the drawing process to almost be played back again) which would get you into databases a little bit.
