I also did something like this many years ago, after finishing my bachelors and I was struggling to figure out what my next steps were. I took it one step further and tried to see if there was some sort of emergent theme that I could overlay over all my various efforts that had some sort of broader meaning to it. I find it enormously satisfying to be able to be able to fit all my various sub-projects, and extracurricular into this kind of network - it makes me feel like I'm constantly pushing some broader goal forward.
