The infinate sword glitch - everyone's favorite. Stops you from falling off edges, but you can get stuck in the air. This is where I try to get down. Eventually ,the crow was the best way.
Also looks pretty
The infinate hoverboot cheat, used in the fishing pond.
Good times. Good times.
The third clip is the least pointless - not sure how, but I got link to be walking about a foot under the surface of the water.
