What should I do?

I take an independent study class in C++ (before you cry foul, the alternative was VB6,) and I am unfortunately at a loss for what to program. Since I design the course myself, I don't really have any guidance on this.

So /prog/, what do you suggest I make?

Make a pacman clone.

Make a Mark V Shaney for 4chan /adv/; markov chains are fun and you get points.

Make a C compiler

- simple web server,
- go client bot with AI,
-

jeez just pick something, anything...editor... do you like graphics, sound?  algorithms?
