I have one I yet to finish. It's called 'Dead in the Snow', which is a comic series I am doing. The basic idea is that Global Warming has the opposite effect than the name suggests. As the world freezes, crops die out and war breaks out just to stay alive. It is the story from three different view points, and UN Specials Ops team steanded in Iraq, now frozen, a family stuck in Southern France, and the various world leaders, fighting the solution out in a bunker. It will be my first comic so don't expect anything special, but I have always loved the concept.
If people like it I will move on to another apocalyptic comic, this time called 'Void'. This is much to complex to explain now, as it still hasn't clicked as a story yet.
Looking even further ahead, I intend to do a Hero Factory stop motion / comic.
