a person with a game controller such as a light rifle could engage in a game whereby targets are simultaneously or sequentially displayed on the ornament displays and the user attempts to shoot the targets thereby displayed. When the user has properly aimed and fired at a target so displayed, the game controller sensor, in this case a light sensor, can register a successful action and product notification thereof, such as by changing the display to indicate the successful action and/or produce one or more sounds via the ornament's, or ornaments', sound generator(s).

"The Victorians had some really strange ideas about what served as an appropriate Christmas greeting," says Bo Wreden, who recently organized an exhibition of holiday cards for the Book Club of California. "They liked to send out cards with dead birds on them, robins in particular, which related to ancient customs and legends. There's a famous quotation from the Venerable Bede about a sparrow flying through the hall of a castle while the nobility is celebrating Christmas: The moment from when it enters until it flies out is very brief, a metaphor for how quickly our lives pass." Apparently, killing a wren or robin was once a good-luck ritual performed in late December, and during the late 19th century, cards featuring the bodies of these birds were sent to offer good luck in the New Year.
