Unfortunately, HTML loses the formatting unless you put it in a code block (which was designed for displaying computer code without losing the indentation). The forum software treats code blocks wierdly, but it does at least still honor the formatting.

Code:
             ----------------->         (motion of thumb)
                     |                  (edge)
                     |
                    ||
                    |||                 (spine)
