Survive as long as I could in my home, then eventually move and get set up on top of a building. I'd try to get it as nice as possible, and I'd just live up there until zombies inevitably broke down the door to the roof, then I'd jump. That way when I die, at least I was living well for the last few days/weeks of my life.
This has been sitting in my "misc. minecraft" folder for a while now. It's got a nice plank texture, a cool stone brick texture and a decent dirt texture. Don't take the side grass texture because it's from the dokucraft continuation project and I was using it as a placeholder. You can have whatever, just give me credit!
EDIT: I've seen community packs that just upload the 32x32 tile rather than the whole 512x512 canvas. It may be more efficient but I'm not sure, just throwing ideas out there.
