I was at Barnes & Noble today and came across a really cool book about the Star Wars models. It's titled "Sculpting a Galaxy: Inside the Star Wars Model Shop"

and its about the design and building of the Star Wars movie models. It looks like it contains great information for scratchbuilding and what it's like to build models for movies (although c.g. is making this a dying art). If you're into Star Wars or Sci-Fi models, you should take a look at this book.Martin
