Meat and Leather producing factory!

The factory is run by a piston machine surrounded by cow spawners. As soon as a cow spawns, the piston activates and pushes the cow off a ledge into a huge cow pen. Once the pen is completely filled, some cows will be forced through an opening into a water tube. The cows drown and the steak and leather is dropped and carried away by the water. The water flows out into a collection area.

If the machine isn't working for some reason there is a trapdoor labeled machine maintenance over the redstone. To fix the machine destroy one of the redstone pieces and replace it with a redstone torch. Then quicly before the power goes around the repeater loop, destroy the torch and put the redstone piece back. The redstone power will go in a continuous loop and power the piston every 3 seconds or so.

I used the single player commands mod to build this. It helped with making all of the cows. If you want to speed up production or just have fun use the command Spawn Cow (# of cows). You can mess around by spawning 1000 cows or something. Spawn Cows1000

Texture pack I used is GeruDoku http://www.minecraftforum.net/topic/72914-32x-14-gerudoku-31-mar-2011-outdated-see-pg100/

If anybody wants I could even upgrade it too collect all kinds of animal loot. I could expand the factory to produce feathers, wool, pork, bones, rotten flesh, and gunpowder.
