Greetings from Cologne, Germany. Yesterday the new Gerhard Richter glass window was unveiled at the Cologne Cathedral. It looks like a group of pixels and is stunning to look at. The line to get in was over an hour and even today, hundreds of passers by simply were staring at the window in amazement. It is great to see how a modern application of old technology can have a positive effect on people. The artist Gerhard Richter, designed the window for free as a gift to the city of Cologne and the over 1 million people who visit the cathedral each year.
Here is one high res version and I am sure many other images will appear soon on Flickr.
