There is a competition sponsored by Amazon and Microsoft to build an application using Amazon Web Services and Microsoft Visual Studio 2005 and submit your contest entry by December 31, 2005. A T-shirt to the first 100 entries and a grand prize of $5000. Sounds a fun way to explore VS and web services - good luck all!

You can find the link at http://www.amazon.com/gp/browse.html/104-5410518-9122333?node=3435361 or go direct.
