This is quite a simple one and I want to get some opinion one it before I start writing. Boils down to an abandoned building (maybe an old hospital) on a small Island North of Russia. Now the interesting thing about the building is that it's constantly shuffling it's self while you're not looking. It doesn't change, it just moves rooms and doors around. Some where there wasn't a door before there suddenly is and it takes you somewhere that before you wouldn't of been able to get to.
Also playing around with it having some inhabitants which aren't found the first few investigations (but presence is felt/heard/suspected) and perhaps even a door appearing that DOES take you somewhere else, like an inter-dimensional hell portal or some junk. I've even knocked up a few pics, though I'm still not happy with the door I've tried to Photo-matte in.
Dya think it's worth expanding and fleshing out?
