Building techniques: SNOT
This constantly growing collection lists different SNOT techniques. It also gives you a list of parts so you can recreate the technique.
SNOT is an acronym for Studs Not On Top - that is, having the studs in another direction than up. In order to utilize LEGO to its full advantage, one must learn to change stud direction. This will let you create shapes that are a lot less LEGO-like. Start by selecting an angle and narrow it down from there. Have a great one we don't? Please send it in!
