(Laughter) So, where does that bring us today? So there are plans. Over in Swindon, the Science Museum archives, there are hundreds of plans and thousands of pages of notes written by Charles Babbage about this analytical engine. One of those is a set of plans that we call Plan 28, and that is also the name of a charity that I started with Doron Swade, who was the curator of computing at the Science Museum, and also the person who drove the project to build a difference engine, and our plan is to build it. Here in South Kensington, we will build the analytical engine.
