The 3D views below are stereo pairs
adjusted for parallel viewing.
You can view these with the naked eye using the same "distant gaze"
method used for
viewing the "Magic Eye" random dot stereogram posters that were

If you have not viewed images like this
before, or are having trouble seeing in 3D,
consult our 3D Viewing Help Page for tricks, tips and information.
