The concept behind a Dyson Sphere had fascinated me ever since I first heard of it from the game Freelancer. After some researching on the different styles and technologies that would be implimented, I figured I'd try painting an audible picture of one.
The layout of 'Sphere' is to be energetic and, dare I say it, pop-ish. For a personal song, that's a little strange, but I'm gonna roll with it. However, I ended up not wanting to rail it onto Sphere's energy immediately, hence 'Joke'. It's made to sound calm and reflective.
Anyway, if you haven't picked up on the concept of a Dyson Sphere, do google it or something. It's massive.
