I subscribed to the Icon Analyst for a while and they had a series of articles about weaving patterns. The authors discovered how extremely insular the weaving industry is - and how dreadfully expensive the software is! But it was very interesting, nonetheless!

(How does weaving fit in with Icon, you ask? Well, Icon's forte is string and pattern processing and doing things with weaves was a natural fit for exploring this kind of thing. :-)
