Minecraft wiki entry for Herobrine, associated text: A popular idea in the community is that Herobrine can be "summoned" through the use of a special arrangement of blocks, such as a "Herobrine shrine" or "Herobrine altar", a 3×3 horizontal square of gold blocks, with a block of netherrack placed on top and 4 redstone torches placed upright on each side. The block beneath the netherrack varies between versions, with common choices being mossy cobblestone, soul sand, more netherrack or more gold. Igniting the netherrack is supposed to "activate" the structure, which then supposedly summons Herobrine into the world.
