Another conference

Just over a week ago I went to London with Infodata for another conference. This time it was all work and no play but nevertheless I managed to spend a ridiculous amount of electronic cash on new clothes.
Even though we didn't spend much time outside the conference room in our Kensignton hotel it was nice to visit London again. The picture above (can you make out where it's from?) was taken on a short walk around the major sights in the city centre.
