This is a fully automatic wheat farm that I've spent the past few hours building. It was build in the 1.8 snapshots. It is designed specifically to prevent the villager from grabbing the harvested wheat.
Une superbe invention de ma part, Villager run apparait sur minecraft, bon jeu dessus. Lien de la vidéo de presentation : http://www.youtube.com/watch?v=v9o9dsMKxM0&feature=youtu.be
This is a medium size zoo on water with animals in it but you are gonna need the mo'creatures mod so download that first and then you can have fun with it.
