I took a topographic map within a 10-20 mile radius, modeled it in some software, and created overlays highlighting roads/highways, demographics, geographical facts, etc. I still have it somewhere, but I'm too lazy to dig it up. I just remember it took a day or so to render it on my school's computer. I also remember my despair when I saw that it had crashed at one point. The teacher who pushed me to do it was literally the best mentor ever.
