Airport interiors are designed to convey a vague sense of serenity and security. Sometimes they do more than that. I’m sitting near a Starbucks alcove inside one of the San Francisco Int’l Airport terminals, and a few minutes ago I felt curiously soothed when I came upon this hanging angel sculpture. So I took a shot of it. And I’m virulently anti-religious. How’s that for a slice of essential 21st Century journalism?
