“Opting out of Google Maps’ Street View in Germany... - Fresser.

“Opting out of Google Maps’ Street View in Germany will blur the image of your building on the photographic map, and make you hideously uncool. So says a group of vandals who egged homes in Essen that appear pixelated on the search engine’s map, leaving notes that say “Google’s cool” (in English) on the privacy-lovers’ doors and mailboxes.
The victims are part of the 3 percent of German residents, totaling almost 250,000 people, who chose to have images of their homes blurred from Google’s Street View map feature. Google uncharacteristically offered Germans the chance to opt out of the system before it launched after German government officials voiced concerns about privacy rights and Google’s data-collection method.”

I like to think that these buildings just look like this in real life.
