Yep. The photo gallery of Minecraft, or, Pilotrange's builds, in particular.
The title is a pun, if you don't get it. Sheet of paper, right?
Yeah, I know. That was a cheesy joke. Moving on to the point, I used a bit of Single Player Commands to do this one. Helps a lot, that.
So, as you can see, I just spawned a bunch of sheep with "/spawn sheep 50" I first had to build a barrier, of course.
This is just a further away picture, as I found out earlier that if you take a picture with about 700 sheep you nearly crash, so I had to move out of the way.
It would be a good wool source, but it would cause a TON of lag and I don't recommend it in your server.
So, basically I called this world "Smiting Things". I used the "/weather lightning" command to smite some sheep and this is the result.
Right after smiting some sheep, they refill the missing area as if nothing happened. Like a wound healing.
