Along the lines of Google Labs, and even, dare I say, our own ResearchWorks, is the MSN Sandbox.
This is the place to play with new MSN technologies, look at prototypes, and peek behind the scenes at some of our new ideas. Let us know what you think about how we can improve MSN for you. Thanks for visiting the Sandbox. [MSN Sandbox]
