Sweet, I've been really waiting to sink my teeth into this one! I have a ton of down time at work so this will be a good one to fill the time. 

Also, I've been hesitant to ask this, but I'll go just go ahead here: What is Expanding Horizons anyway? Is it based off of a book/game/movie or is it something totally community-built here? It seems way cool, but I tried to figure it out on my own through Google and what I found doesn't really compute right across to this particular subject.
