Several stereo images were taken with this system, one being particularly good, numerous promising ones and several unsuccessful. The best image was of a box angled to clearly have a corner nearer to the camera than the diagonally opposite corner, in an effort to perceive the depth of the box. Despite one of the cameras being slightly out of focus, the depth of the box was perceived quite well in the (stereo) displayed image.

One notable problem with this early system was that the left and right eye images were often not taken simultaneously. This is because the system was constructed from shell scripts and the Unix rsh utility, both of which can be slow and dependent on the system and network loads, thus resulting in uncontrollable (and unpredictable) time differences between the capturing of the left and right images.
