I have known Jeff Barr for many years and am envious of his job: he basically gets to work on cool stuff at Amazon.com and tell people about it. He developed a Second Life application that models what he is trying to do with various Amazonian Web services and produced this short video that gives you a small taste of what he is doing. Way cool!

Yes, there is plenty of non-business related things going on in Second Life, especially people that are hooking up to each other. But this demonstrates the power of showing you how various pieces of code can hook up to each other in a way that would be difficult to do in the real world.
