This was common 20 years ago, but has been largely replaced by the use
of true stereo, e.g. Zalman monitors, for interactive viewing.
Side-by-side is still used for publication (usually relegated to on-line
supplementary material these days).
In any case the plots one would want this for are not the sort of thing
that gnuplot is good at. We use specialized programs that know about
protein structure, crystallographic data formats, and relevant conventions
for display of chemical features.
Try an image search for "protein active site stereo" in Google.
