Any ideas where i can find these?

[Rich Nello]

Hi all,
I am required to find an interesting program (apps or games) on the web and download the 'original source code'. The program itself doesn't need to be loo long. In fact it can be quite a small program!
Then, I need to modify it using concepts we never covered together at university! (like threads, GUI, Security, DB Access etc ...).
If it was a game we downloaded, (like TicTacToe) for example, we could modify the colors, add moves etc ...
I'm finding this idea very daunting since the programs i'm coming across all seem quite 'complete' and most of them are applets (which we didn't do either!)
I was thinking that if I found a console application, not an applet, I could download it and then try (with lots of positive thinking!!) to convert that to GUI!! But my question is: are there any sites that fit into this category?? Will I find simple applications which i can understand and eventually work on and modify?
Please help, any suggested site would be appreciated.

Here's a Tic-Tac-Toe for the console, try to build a GUI for it.

errrr! Thanks!!
But do you know of any web sites where i could look and maybe download a few applications?
Besides, i cannot use code without a source to map it to.
Maybe I can get a few options that way??
But THANKS for your reply!

Planet Source Code is worth a look, follow the links to the Java section
