Since Summer is over now and kids are going back to school, thought it would be fun to do one of those "what I did over summer vacation" videos. Here, catch Austin Donnelly taking us around downtown Cambridge England. Who is Austin? He’s a Microsoft Researcher (got a PhD). See Cambridge's awesome architecture and go "punting on the Cam" with Robert Scoble, his wife Maryam, and Austin. Yes, we go under the mathematical bridge.
