This is what happens when I get bored at 4am. I was just tooling around in The GIMP and ended up traveling through many realities. On my journey, I found something. It's a creature that lives in aluminum cans and wears gas masks, and lives in the land of skycoal, where there is sky, and there is coal. It is also apparently invisible. Many of these creatures have been found decoraing the exterior of their houses with discarded items that appear to originate in the human world. Nobody is sure why - we've just now discovered these beings, but they apparently already know about us. We wonder what relationship they have with us. Perhaps they're watching over us as curiously as we will be them.
