Hidden Object Pictures:
Hidden object pictures have a long a history. Hidden object postcard-size images became popular in the mid 1800s.
By the late 1800s hidden object puzzles were common advertising vehicles for a variety of products such as sardines and cigars.
Dual Object Pictures:
Dual object pictures are commonly identified as optical illusions rather than puzzles. The following “old and young woman” being the most famous.
Another famous dual image is “A woman at her vanity” which uses the double image to convey a message, “vanity is a deadly sin.”
Most modern dual object pictures feature skulls or other halloween imagery. The point being that it is a shock for the viewer when they see the second mildly hidden image.
Hidden Object Books:
The most famous hidden object picture books are the “Where’s Waldo?” series. The point being to find Waldo midst a plethora of distractions.
Graeme Base’s “Animalia” takes another approach, every page is devoted to one letter of the alphabet and the illustration is filled with animals who have names starting with that letter. The challenge is to identify all of the many animals represented.
Walter Wick’s “Can you see what I see?” series puts a modern polish on the traditional hidden object puzzle.
Hidden Object Video Games:
Hidden object video games are exactly what they sound like, games where you find hidden objects. While the cerebral challenge of these games is low, they provide mild entertainment much like playing solitaire boggle.
