Greetings, fellow Minecrafters! Today, I want to share with you one of my favorite redstone contraptions: the 2x2 Jeb door. This is a type of hidden door that uses the famous rainbow sheep's color-changing feature to create a mesmerizing effect. The door is not only functional and secure, but also visually stunning and fun to build.

Let me explain how the door works. The name "Jeb" comes from the Minecraft developer Jens Bergensten, who implemented the color-changing feature for sheep in a previous update. This feature can be exploited to create a hidden entrance that blends in with the surrounding blocks. The door consists of four blocks arranged in a 2x2 pattern, each with a different color. When a sheep is named "jeb_" using a name tag, it starts flashing different colors randomly. By placing the blocks in a specific order and using pistons, observers, and redstone, we can detect the sheep's color and activate the door accordingly.

The beauty of the Jeb door is that it can be customized in many ways. You can choose any combination of colors for the blocks and the sheep, depending on your preference or your building style. You can also add other features to the door, such as a secret button, a trapdoor, or a dispenser. The possibilities are endless, and the result is always satisfying.

One of the advantages of the Jeb door is its compactness. Unlike other hidden doors that require a lot of space or resources, this design is relatively simple and efficient. You only need four blocks of space, four pistons, two observers, and some redstone dust and repeaters. The rest is just a matter of following the instructions and placing the blocks in the right order. You can also download pre-made schematics or watch tutorials online to guide you through the process.

Another benefit of the Jeb door is its security. Because the door is hidden and requires a specific sheep to activate, it's virtually impossible for intruders or mobs to enter your base or house without your permission. You can also disguise the door further by placing it behind a painting, a bookshelf, or any other decorative block. This makes your day :)
