Depending on the location of the room and proximity to other rooms, I think you should add some water and/or lava flowing down the walls. Then, use it as a room to test some basic redstone contraptions and store a few odd items.
Bring a couple of beautiful girls in there, have a mutual conversation and maybe bring some steak with and have a nice meal.
Invite the girls over a lot and then get married to them. Have kids and do everything in that room.
Once the kids get a little older, kill the mother/mothers and have kids with your children, then slaughter your children and teach your down syndrome kids to play hockey. They will be the greatest hockey players the world has ever seen.
