SNOT search engine
This constantly growing search engine lists different SNOT techniques by size and angle. It also gives you a list of parts so you can recreate the technique.
Wondering what SNOT is? In the LEGO world it's not as yucky as in the real. 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 it's full advantage, one must learn the sacred art of changing 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!
