Minecraft wiki entry for Building_a_metropolis, associated text: Interior Design Nobody wants to live in a house without furniture! In every house you build (you should end up building a lot of them), add special furniture. Use pistons or fences with pressure plates for tables, stairs and signs for chairs, and bookshelves to decorate your houses. Try making a computer with an iron block and a painting, plus redstone and a lever to be a mouse.
