Hi All,
 This autostereographic technology is sold by a number of companies:
 Dynamic Digital Depth
 http://www.ddd.com/index.asp
 Stereographics
 http://www.stereographics.com/products/synthagram/synthagram.htm
 Dimension Technologies, Inc.
 http://www.dti3d.com/products.asp
 4d Vision
 http://www.4d-vision.de
 SeeReal Technologies
 http://www.seereal.com/EN/products.en.htm
 Autostereo technology works by slicing multiple images vertically into
 individual bands and interleaving these bands into a final image. This image is
 viewed through a lentiule so that each eye only sees one set of bands.
 Here are some questions you may want to ask about the technology:
 1. Does the display work both as a standard 2D display and 3D display?
 For example, SeeReal Technologies only works in 3D.
 2. What video cards are needed to support the display?
 3. Is the technology plug-and-play and does it work in real-time?
 Some autostereo displays use standard stereo-pairs, i.e. two perspective views,
 one for each eye (e.g. SeeReal Technologies). They are compatible with existing
 stereographic applications. For example, according to the SeeReal website, their
 LCD display works with Accelerys Viewer Pro. It also seems that if the software
 supports stereo shutter glasses via OpenGL , then it should work with any
 molecular graphics program that does so, such as VMD, Pymol, Cache, etc.
 Other systems require more than two views: 4D-Vision (8 views) and
 StereoGraphics (9 views). These systems allow for looking around objects and for
 multiple users. The downsides are:
 a. lack of compatibility with existing stereo-content
 b. need of multiple cameras: 7 to 9 cameras (virtual or real)
 c. not real-time, because the the images from each view are preprocessed be
 interleaved into a final picture; then are show
 using a viewer.
 SeeReal's technology obviates these problems by using eye tracking technology.
 As the viewer moves in front of the screen, an eye tracker mounted atop the
 display keeps track of eye positions, the software then updates the image for
 the current viewer location, essentially by sliding the bands into the correct
 viewing position. The possible downside to this technology is that it is correct
 for only one viewer.
 4. How much detail can you afford to lose?
 Interleaving of images means fewer pixels per view. For example, interleaving
 two images to fit on a 1280x1024 display means that each image is 640x1024.
 Using more  images means further degredation of detail. Yet resolution is
 increasing. Some of the newer autostereo LCD display systems work at 1600x1200.
 Finally, both the Stereographics and SeeReal website give good descriptions of
 the technology. Here are some interesting websites and papers:

 http://www.evl.uic.edu/paper/pdf/autostereography.pdf
 http://www.mrl.nyu.edu/publications/autostereo/spie2001.pdf
 At this moment in time, no stereo 3D technology is perfect, but it is fun to
 play with the all the technology.
 Have Fun!
