Sup guys.

A little background:
I'm a computer science major in my 3rd year of college. Im trying to figure out a side project to do in my spare time. I've taken classes where we've used Java, C++, and more Java. The class I'm taking right now is Systems Software and we are doing C and earlier in the semester we did a little Shell programming on Linux machines. Some little projects I've done is a blackjack game, a mini student database where you can add/delete/modify/sort/and search for students, and things of that sort. Also, I've never done anything visual with programming so that could be a possibility but im also stating that so you dont come in and assume i know how to do any visual stuff. Everything I've done has just been output on the console or to a file.

I'm trying to figure out some side projects i can do that could be fun/help me learn more but I'm having trouble thinking of what to do. So if you all know any good side projects that could be fun/help me learn more please feel free to post them, I'm open to all suggestions right now.

Thanks!
