How about a little group project for some light entertainment? This project has no specific aim, and anyone can contribute by adding/changing whatever they like, as long as it meets the rules. To do so take the most recent version, add something to it, then post it back.
The rules are simple:
1) Each new revision must compile with g++, but may have bugs in it (deliberate or not).
2) Only standard libraries can be included.
3) New versions should describe roughly what was changed.
I'm sure that between the lot of us we can come up with something amazing. I attached something to start off with.
