Tasty breadcrumbs
Many of the samples here are fairly well known, others are not. All in all this is a pretty large and in depth look at a variety of styles in breadcrumbs. I find that this is another one of the many web elements that all to often gets under appreciated and so seldom included in a design even though it provides a lot of help to the user of the site.
