I love building in minecraft just as much as I love the idea of random mobs attacking me while I build. However, I don't like it when I'm just walking out my door after a snooze and a creeper didn't get the memo and was hiding on one side of my house and sneaks up behind me as I walk out and does an amazing job of remodeling my front door wall.
What I'm hoping for is something that will prevent this terrible thing from happening. I've tried fences but they still blow up if you are on the border of the fence and you happen to be unsuspecting of their approach. Some good building techniques would be great for anticreeper measures.
