What does an ExtroBritannia event look like?

If you have never been to an ExtroBritannia, here is your chance to see what the November 2004 event was like. Our guest-speaker was Aubrey de Grey and the topic was life-extension promotion via the Methuselah Mouse Prize. The venue was our Conway Hall, our usual venue for the more formal events (often we simply meet in a pub or restaurant).
