Hey look: http://www.schmap.com/berlin/tours_tour3/p=198396/i=198396_24.jpg
It's a photo I took being used to illustrate the Topographie des Terrors in an online guide to Berlin. I let them use the picture (which is actually just a hotlink to it on my Flickr page) for the fame that this will bring me. I am sure that seeing this picture will make many other people realise what a great photographer I am, and so I will find myself being offered huge sums to have my photographs included in coffee-table photography books.
I have to admire the business model of the Schmap guide people... get people to let you use their pictures for free, then have them publicise the guide for you by telling all their friends about the pictures being used.
I recommend Berlin's Topographie des Terrors exhibit highly. It is one of the few places in the city where the Third Reich and the Cold War periods of the city's history collide, with the exhibition (in what were once cells in the basement of the Gestapo headquarters abutting onto a surviving section of the Berlin Wall. The open-air exhibition deals with the Third Reich's apparatus of repression. When I took the picture, it had been snowing... trudging through snow and slush to look at information on Nazi crimes seemed oddly appropriate.
