Is anyone working on this addon or is it already incorporated in something? I think it would be amazing if this could be done, It would really add another layer to the minecraft experience, It would be great to creep people out with it, I know it would creep me out having Herobrine just standing there staring at me from around the corner in the semi dark then disappear as soon as you get near him compared to getting a hug from a creeper. Which is more funny/cute/annoying then creepy. I think it would encourage people on public servers to work together more and interact because some of the people who know the story would get freaked out and would rather stick with others, it would also help spread the story around again, I think minecraft could use a good ghost story! If you can set it so it only happens when people are on their own perhaps? When there is nobody else in a 20/40 block radius or so and only in dim light, dusk/edges of a torches light, and at night just the glowing white eyes? Not sure if that's possible. But it should only be occasionally and to random people, If it happens every time someone is alone it wouldn't work, just now and then.
