For a hobby that revolves around dead people, genealogy is remarkably popular: it's the fastest-growing scene in North America.

See all of this with hands-on demos and our top-10 list of stuff to know about WPF and Microsoft Expression Blend. And, unlike the real-world case studies, you get the source code.
