The most beautiful Minecraft piston door

My name is Oli, also known as Mumbo Jumbo and I make videos on the popular voxel based game 'Minecraft'. I focus mainly on the technical elements of the game, doing tutorials on various elements of redstone to try and make you better, and hopefully give you something you can show off to your friends. I also have a long running Vanilla Survival Let's Play series on the well known Hermitcraft server.
