It makes humans feel right at home. At the same time, always check out the windows.
They aren’t for seeing into, as alleys are, but for giving you eyes in the back of your head, and multiple perspectives at once. And while you’re at it in Reykjavik, always pay attention to advertising posters. They are the user’s manual for the art installation.
Note how the sign is a smart phone screen, the guy on the right has the idea, as do the tourists behind the woman in red. Well done, everyone!
