I was reading Kepler's Epitome of Copernican Astronomy and The Harmonies of the World recently, and found myself quite fascinated with his Platonic solid model of the solar system. On a lark, I set about extending it to include Uranus and Neptune. It proved to be an interesting challenge, and one that really helped me connect with the mindset of the age better.
Of course, with all that done, I had to write up my results as a full academic paper: Extending Kepler’s Mysterium Cosmographicum
