Takayuki Fukatsu has created a pretty cool Flash application that allows you to see related items from Amazon.com. Starting with a simple search box, you type in a subject or book that you're interested in. Takayuki's Flash application makes a series of API calls back to Amazon, finding books that people are related to the one(s) you've searched for, using Amazon's 'people who bought this item also bought this item' API. After a few seconds, you get a cool visualization of related books. Check out this search for ActionScript 3 books on Amazon to see an example.

The site is done using Flash and ActionScript 3. The application is all the more impressive when you consider that ActionScript 3 for Flash is only available as a right now.
