Rob Miles of the department was one of the presenters at Microsoft EMEA TechEd 2008 in Barcelona. This is hot on the heels of his presentation at Microsoft USA TechEd 2008 in Orlando. Both times he was talking about the .NET Micro Framework, a particular passion of his. This time he took a whole host of hardware, including the Christmas lights, for his talk "EMB207 Putting Your Big Ideas onto Tiny Devices with .NET"
By all accounts the talk went well, and all of the demonstrations (including the big finale when Rob makes his Christmas tree lights flash red when he updates his blog) worked.
