Pattern Stories are descriptions of systems that include patterns. Pattern Stories are good ways to learn about a pattern, but they also can teach you about various problem domains.
The Pattern Stories Web is a wiki clone that contains stories of uses of patterns
http://wiki.cs.uiuc.edu/PatternStories (BrokenLink 20070524)
It is a good place to go if you want to hear how someone used Observer Pattern, or if you want to share your own stories.
Eric Huss created the engine, which he calls Wikic Web, but I'm working on the content. Stop by and take a look!
