Good idea!  What about "hypercyclopean"? :-)
As mostly, I'm half serious. See what Tyler and Kontsevich
wrote in 1995 in the journal "Perception". Tyler was the inventor
of the single image random dot stereogram, also known as
autostereogram. That technique is used in the article.
The paper was originally delivered to an international meeting,
and was chosen as the first paper to appear in a special
issue of the journal, to which Brian Rogers (of Oxford) wrote
the editorial.
The whole article is 27 pages, the summary is half a page,
I only quote excerpts from the summary.

"Mechanisms of stereoscopic processing: stereoattention and
surface perception in depth reconstruction."

>>Consideration of the range of phenomena from studies of human
stereopsis suggests that a five-stage model is required to
provide a complete account of the processes involved, within
which any stereoattention mechanism must operate.
The information from the disparity field of the optical projections
to the two eyes (stage 1) goes to a set of parallel Keplerian
arrays of disparity detectors, each array selective for a different
spatiotemporal property of the visual images (stage 2).
Global interactions produce a cyclopean depth image that is cleaned
of the spurious ghost images in the Keplerian arrays (stage 3) and
that may then be processed for its (hypercyclopean) form elements
(stage 4).<<

>>Finally, there must be a stage of integration of the
stereoscopic depth cues with monocular and kinesthetic depth
cues to form the overall map of perceived distance (stage 5).
The fact that multiple cyclopean surfaces may be perceived as
transparent implies that the stereoscopic system is not limited
by a singular-surface constraint. However, it is unclear whether
multiple surfaces can be seen simultaneously or whether only one
surface is seen at a time by a selective-attention process, with
the others perceived as a purely inchoate (qualitative) depth
impression.<<
