Minecraft wiki entry for Furniture, associated text: Alternatively, you can use the item frame method to set up a computer. Place an oak wood block next to the wall. Above it on the wall put an item frame. On the wood block, put a stone pressure plate and there you have it! You can put a map or an item (heads are good ones) inside to make it look like you are running a program. You can also expand by putting another block of wood on one side of the first one and placing a empty flower pot on one and a button of any type on the other. You now have a laptop with some coffee and a mouse!
