Looking at other web sites
As discussed in Creating a custom web site, there is a lot to be learned by looking at other web sites for ideas. I found this site interesting:

It is a totally Flash site, which I would not recommend as a general rule because of indexing problems and (in many cases) cost issues. However, it has an unusual but helpful navigation tool that may be useful in other projects, and the look of the site is very clean.
