Microsoft's TechFest 2007 R&D blowout

So for the first time in its 15 year history, Microsoft Research's TechFest showcase for internal R&D projects was opened to the public. We headed up to Redmond to check out what some of the Microsoft engineers were working on behind the scenes, some of which went live as products, some of which we won't see for years, and some of which we may never see productized at all. We understand there's still some more internal-only TechFest stuff going down this week, but check out our gallery from some of the wacky concepts, prototypes, and products we think you'll get into.
