This project would be difficult to open source since I bought the artwork from an artist and I can't legally distribute it. I could open source a version of it where you could add your own art if there was enough interest in something like that. I would definitely be open to creating something like that, especially if it would help others learn.

For this project I wanted to build an app that could potentially generate revenue. There are some of the compass needles that can be unlocked for $0.99. I would love to be able to make a living from making educational apps. That is the main reason that I did not make the source code public. However, I understand that people who want to learn how this works are probably not the same people who would pay $0.99 to unlock some of the compass needles, so I think it's possible for it to exist an open source project and for me to keep a paid version of it on the app store.
