cool C++ program ideas?

[Desoxena]

Hey, I've been at C++ for a few months now and I am finally starting to really get my head around it. I have pretty much exhausted all of my program ideas that I could even think of. So do you guys have any cool ideas for programs?
Here are some of the programs I have made:


Note: these are all console programs

1. little animation thing
2. string reverser
3. simple login script
4. tic-tac-toe
5. string translator(vowels - >0's and consonants -> 1's
6. number pyramid
7. grader system
8. logbook (keeps recent entries in a separate text file.)
9. list-maker

note[2]: you can also find most of these scripts on 'Snipplr'.

How about the programming missions here?

There are lots of sites where you can find lists of various challenges or things you can try out. For example:
http://projecteuler.net/
Project Euler has lots of small missions as such. I would personally suggest searching on google though as you can then browse lots of forums where people have listed off answers to the very same question you have asked.
