I don't why the poll, just guessed it would help some how. Anyway I didn't come into this with any ideas. But now since you mentioned it I thought of a few like, advance Calculator, a city builder, a space adventure, a batch file manager. An since this is the first really new thing I tried on this forum. Maybe these projects could be written in multiple languages, via C++, python and java. Plus if multiple people help, some people might not need to speed massive amounts of time. The code of these projects could range from 20 to 1000.
So that's all the questions I saw, but the reason I didn't post some code, was I didn't have any. Other people can come up with more ideas then I can. And If anyone wanders why, I am very bored after school and practice, so i want to help people and program random things.
Thanks for all the feedback anyway!,
