An autostereogram is a single-image stereogram (SIS), designed to create the visual illusion of a three-dimensional (3D) scene from a two-dimensional image in the human brain. In order to perceive 3D shapes in these autostereograms, the brain must overcome the normally automatic coordination between focusing and vergence.

The simplest type of autostereogram consists of horizontally repeating patterns and is known as a wallpaper autostereogram. When viewed with proper vergence, the repeating patterns appear to float above or below the background. The Magic Eye books feature another type of autostereogram called a random dot autostereogram. One such autostereogram is illustrated above right. In this type of autostereogram, every pixel in the image is computed from a pattern strip and a depth map. Usually, a hidden 3D scene emerges when the image is viewed with the correct vergence.

Autostereograms are similar to normal stereograms except they are viewed without a stereoscope. A stereoscope presents 2D images of the same object from slightly different angles to the left eye and the right eye, allowing the brain to reconstruct the original object via binocular disparity. With an autostereogram, the brain receives repeating 2D patterns from both eyes, but fails to correctly match them. It pairs two adjacent patterns into a virtual object based on wrong parallax angles, thus placing the virtual object at a depth different from that of the autostereogram image.

There are two ways an autostereogram can be viewed: wall-eyed and cross-eyed.[1] Most autostereograms (including those in this article) are designed to be viewed in only one way, which is usually wall-eyed. Wall-eyed viewing requires that the two eyes adopt a relatively parallel angle, while cross-eyed viewing requires a relatively convergent angle. An image designed for wall-eyed viewing if viewed correctly will appear to pop out of the background, while if viewed cross-eyed it will instead appear as a cut-out behind the background and will be difficult to bring entirely into focus

There are many people who want to know if they could obtain a free Windows Vista copy. This is because there are a lot of people who are simply not willing to pay the amount of money that it cost to in the store to get a copy of Windows Vista. There are few ways that some people obtain a free Windows Vista copy, but they come with their disadvantages.

The main way that people obtain their free Windows Vista copy is by using the Windows Vista Black Edition. The Windows Vista Black edition is a pirate copy of Windows Vista. It is the original Windows Vista operating system that has been modified to be a custom OS. It has many programs and features that are not included in the original copy of Windows Vista. This free Windows Vista copy can be downloaded using torrent programs. Torrent programs are programs such as UTorrent, BitTorrent, and several other free programs that are available on the internet. When you download the torrent program you will have to find the torrent file that is linked to the Windows Vista Black Edition. That file will tell the program how to download the installation files for Windows Vista Black Edition. The torrent file for the Windows Vista Black Edition can easily be found by searching for it on Google's or Yahoo's search engine.

The Great Plains Black History Museum is located at 2213 Lake Street in the Near North Side neighborhood in North Omaha, Nebraska. It is housed in the Webster Telephone Exchange Building, which is listed on the National Register of Historic Places. A nationally renowned institution for more than 30 years, the museum includes more than 100,000 periodicals, manuscripts, photographs and research materials.[1]

It is the largest museum devoted to the black experience on the Great Plains.[2] The facility has been closed because of needed renovation but, as the new president says, "The museum is open." As of the spring of 2011, a new board was in place which was holding community meetings to broaden discussions of the museum's future.
