SUMMARY: The images below are our continued attempts to apply cross hatching techniques, such as those employed in pen and ink drawings or Albrecht Durer’s etchings from the renaissance to flow visualization. With this set of visual explorations, we are applying a ‘ribbon metaphor’ that DAS found in a journal article (directly below).

The images below are posted in reverse chronological order, with the most recent sketches toward the top of the page.

3. #2 below, with the ribbon amplified by reducing surrounding details.
