We enjoyed preparing and giving this talk very much. Thanks very much to the people who attended and for the interesting questions and discussion, all of which contributed to the talk's success.
It's the first time that I have made a presentation using Prezi (http://prezi.com). Prezi allows the presenter to zoom around a large canvas and get away from the intrinsically serial nature of traditional presentation tools. It suits my style and was well received by all that I showed the results to (I've heard of some feeling symptoms akin to motion sickness as a result of the zooming and rotation). I'll be continuing this experiment with my next presentation at Agile Central Europe in Krakow Poland on 8-9th April.
Many thanks also to those who mentioned our talk in their post-gathering round-ups. Here:
