What Should My 3rd Project Be?

Hey, I am pretty new to VB and was wondering what you would recommend I should do for a 3rd project?
I have currently made a text editor that allows you to save, open, print, make text bold, make text italic, make text underline. Ive made a app that allows to computers to comunicate with winsock, it displays when the last message was recieved, lets you put in a chat name. Im still working on this as I have a lot of bugs to fix in it still.
Anyone any ideas what kind of a app I should try and make next?

Something with a database would be good, as would something that Automates an Office app. Both are very useful to know well.

I was thinking of doing something with a database, I cant find any tutorials though :(
