This pixel-sort glitch of the Cologne Cathedral is based on a photo, I've shot with my mobile phone several years ago. In Germany everyone knows this famous cathedral, but especially when you live so close to Cologne, like I do, you just can't ignore it. Most remarkable, it took 632 years to be finished. "It is Germany's most visited landmark, attracting an average of 20,000 people a day, and [...] the largest Gothic church in Northern Europe [...]. The towers for its two huge spires give the cathedral the largest façade of any church in the world."
