Armor Stand Overlay/Block things

X Y Z are the block's position that you want to summon at.
You can also, once the stands are in place, teleport them to '~ ~ ~ 180 0' and '~ ~ ~ 0 0' to vary how they look on the block. The center value of each pose (0.0f) can be altered as well to (0.01f) to remove the glitchy look of the blocks displayed, however the bottom of the 'block' will look a bit slanted.
Use /replaceitem to swap the head blocks in the armor stands
