Here's a recording of a talk I gave last night in the ISKS series of conversations organised by Prof Peadar Kirby. The talk went well and, more importantly, the conversation was very interesting. Dr Finbar Bradley made up the other side of the conversation, based mainly on his new book.
The talk wasn't designed with slides, but with Prezi.com, a really cool little piece of free software. Have a look at it here.
