Easter egg (virtual)

A virtual Easter egg is a hidden message or feature in an object such as a movie, book, CD, DVD, computer program, or video game. The term draws a parallel with the custom of the Easter egg hunt observed in many western nations. In computer programming, the underlying motivation is often to put an individual, almost artistic touch on an intellectual product which is by its nature standardised and functional. It is analogous to signature motifs such as Diego Rivera including himself in his murals or Alfred Hitchcock's legendary cameos.
