On Saturday the 6th December I was invited to do a talk about motion timelapse at an event set up by Triggertrap to create the world's first crowd-sourced timelapse of London.   I've not done much in the way of public speaking since I was asked to do a reading at church when I was a kid and subsequently broke down into a blubbering mess, overcome with emotion, nerves and not liking the whole 'situation'.  What could go wrong?
