Putting together a new campaign world

I put together the premise behind a new "sandbox"-style campaign, along with the geologic, botanic and economic portions of the map. Need to do the demographic portion, still, as well as follow the intersections into the other planes. Then comes the political, followed by finishing the biome and building the NPC cast. I'm going to need HTML, CSS, JS and transparent PNGs to tie this all together, legibly.
