This writing direction comes from the lost script of Rapa Nui (Easter Island). The text was written in "reverse-boustrophedon" for smoother, uninterrupted reading and writing. Rather than moving the writing implement or the eye down one and to the left to begin writing again, the scribe would simply rotate the surface 180 degrees or in the case of cylindrical objects such as the staff pictured, simply turn.
In my experience rongorongo text is more comfortable to read than boustrophedon.
I'm using the OpenDyslexic font for this. OpenDyslexic's asymmetries make it harder to mix up letters like "b" and "d" when reading text with an alternating direction.
