Comments: This is the first ASCII stereogram I've put together (for my
HP email newsletter). If you haven't tried this stuff before, some hints:
% You have multiple representation of objects in parallel columns -- 4
in this example.
% An object nearer to you has *closer* spacing (fewer spaces); an object
further away has *wider* spacing (more spaces).
% With four columns, in stereo you will appear to have *five* columns.
You can see spacing errors by inspecting the center three columns (the
two outlying columns don't count -- they're hard to focus on).
% Beware (as I got trapped initially) to make sure you have a common
number of representations of *all* objects. Originally I had three
representations of a few objects, but this led to a visual conflict
with objects that had four representations -- a very subtle one since
the spacing was correct. So I went back and made sure I had four
representations of every last element in the picture.
