Please contact me (preferably via Skype) if you would be interested in creating the next update's splash screen. I have a set of (fairly loose) requirements, but there's a not-too-distant deadline. I can personally reward the artist who 'wins' this contest with a user title and a mention in the release notes, plus you get to see your artwork every time you start the game.
Bonus points if you're interested in doing the finishing touches on @Swordmaster's political map, which is nearly done. I have the Photoshop files saved, and can forward them to anyone interested.
"You see what your knowledge tells you you're seeing. ... how, what you think the universe is, and how you react to that in everything you do, depends on what you know. And when that knowledge changes, for you, the universe changes. And that is as true for the whole of society as that is for the individual. We all are what we know, today. What we knew yesterday, was different; and so were we."
- James Burke, The Day the Universe Changed (1985)
