I will speak at the next pecha kucha night in Cologne on 20 November 2014.
The topic will be my photographic documentation of Speakers' Corner.
Update 24 Nov 2014:
Ok, that went well. After my talk I was approached by organizers of pecha kucha nights in other cities. I was asked to do another six appearances :) The next will be this Friday in Düsseldorf.
Update 23 Dec 2014:
My talk from 20 Nov is now available online. I talk 6' 40" in German. Sound and pics are a few seconds off but that will not keep you from enjoying the talk. It only hurts my ego because I pride myself on my timing.
