An Airport Security Game That Rivals the Real Thing - New York Times

Sign of the times... 

As little animated passengers march up to the checkpoint, you must click on icons of various prohibited items depicted in their carry-on bags or on their persons, while not letting the lines back up. (A laptop without a mouse is not advisable).

The trick is, news flashes on the bottom of the screen keep changing the rules on what’s allowed and what’s not. You have to be quick to click on newly prohibited or allowable items, among them Sioux war bonnets, tubes of Preparation H, cattle skulls and conch shells.
