This is a quad sided self-building wall, which uses 4 rows of pistons, lava, and water to make a wall that builds from 4 different sides. Broken blocks are replaced very quickly, and come from different directions, which has a very interesting visual effect. This wall utilizes obsidian to stop this four sided wall from destroying itself when it is rebuilding. However, a very large wall could use the push limit of pistons to prevent self-destruction.
In my last video, I mentioned that a wall could be made that repairs from all four sides. Well... I went and did it.
