Further Development
The name 'random dot stereogram' specifically refers to pairs of images based on random dots. Additional work by Christopher Tyler and Maureen Clarke led to encoding the same data into a single image which did not require a stereoscope for viewing. These are known as Single Image Random Dot Stereograms (SIRDS), or Random Dot Autostereograms.
Replacing the random dot base pattern with an image or texture gives the form that made the Single Image Stereogram known to the general public, through the Magic Eye series of books.

Famous quotes containing the word development:
“... work is only part of a man’s life; play, family, church, individual and group contacts, educational opportunities, the intelligent exercise of citizenship, all play a part in a well-rounded life. Workers are men and women with potentialities for mental and spiritual development as well as for physical health. We are paying the price today of having too long sidestepped all that this means to the mental, moral, and spiritual health of our nation.”
—Mary Barnett Gilson (1877–?)
“The man, or the boy, in his development is psychologically deterred from incorporating serving characteristics by an easily observable fact: there are already people around who are clearly meant to serve and they are girls and women. To perform the activities these people are doing is to risk being, and being thought of, and thinking of oneself, as a woman. This has been made a terrifying prospect and has been made to constitute a major threat to masculine identity.”
—Jean Baker Miller (20th century)
