Another weekly snapshot

So, there have already been two snapshots released today, the second being a huge bugfix from the first. This one adds things like waves of zombies sieging villages, villagers reproducing to make up for the deaths overnight, increased world height, and light sources that can be turned on and off with redstone!
I don't have a video yet, but I should have one up in just a few hours showing off some of this cool stuff. Have you found anything interesting in the snapshot I missed?
More information and the official download can be found here

Wow, Creepers and Kitties, eh?

So I threw together a little video having fun with the new AI stuff in the weekly snapshot. It really wasn't much, just me playing around with an idea I had from DocM's video earlier today. So I uploaded it and posted it to Reddit, and people actually liked it!
