Keeping an eye on the prize

摘要

There was a day when a private investigator, or "private eye," just was a detective. Not anymore. Today the term also applies to a neat program that protects a user's screen from prying eyes, allowing for an occasional forgetful moment, such as when one fails to invoke the screensaver when headed for the coffee machine. Or it shows you the picture of someone behind you if they are shoulder-surfing at, say, an airport lounge. The thing about this PrivateEye, though, is that it is so simple in operation. That, of course, is one of its beauties.
