Minecraft wiki entry for Furniture, associated text: Another way is to place a painting on the wall in front of a block of wood and place a minecart rail or another object that looks like a computer keyboard and you can use that as a computer. When you want to 'change the display' just put a new picture in place. A really good way of making a keyboard is digging a one block deep hole, and then putting a carpet on it. Then, put two armor stands facing forward on the left and right side of the hole. Using pistons, push the armor stands into the hole. Now push a quartz block downward repeatedly (again, using a piston) until it reaches ground level. There you have it, a keyboard.
