I like hard science fiction, where the science is as close to reality as possible.

I wanted to make 3 dimensional star maps of a hypothetical interstellar empire and its closest neighbors. I used the Hipparcos star catalogue and the mathematics of close packing of spheres.
Boy, did I go down a rabbit hole!
