I just noticed that the document is in XLS format, though it is seen running in
Calc. (On a Mac?) 

The AC/DC ASCII-art video (one I first saw in an XLS format a couple of years ago) as done
in ODS doesn't use any Windows-specific objects.  The narrative explaining how that one was
done (linked by Andrea) goes into that.

Cool.  How would we get the pixel level numeric data into the
spreadsheet initially?  I assume there is nothing in the macro
language that can parse image data at that level. So we'd need to call
out to a helper library?

Also, one other nice time to have -- not strictly necessary, but would
improve the results -- picking an optimal color palette that best
matches the colors in the original image.  There are some standard
algorithms for this:
