Minecraft 1.5.1 Slaughterhouse
This is a prototype Slaughterhouse I designed. It can be as long as you want it and as tall as you want and kills the cows by drowning them. Drowning seemed to be the most efficient and cost effective method. The grass growing feature is kind of pointless and was more designed for when i envisioned it as sort of an auto-pasture where that type of thing could be useful. The last part was just a peek at the beginning of my transportation network.
