Minecraft: Protect your original spawn point plus a new 1.8 passive mob system!

Inspired by Etho I created a new 1.8 world with his seed. I'm hoping he decides to protect his original spawn point and here's a suggestion on how to go about it. It includes a bed, crafting bench and furnace as you may expect but it also has some bonus features. A simplified quick kit design, a compact hostile mob system and even a new 1.8 passive mob system!

Sorry for the demo capture software, I'm broke and can't afford to buy anything except food.

If you need tutorials on any of these features let me know.

Enjoy!
