Yes, pretty insipid. I suppose it is supposed to be iconic, but that never really works (one culture's icons are another's blobs). I do suppose that the 'mani' sign is a bull or some such, since 'mani' basically means "cattle, herd animals as wealth". The other signs range from the obvious (to us) to the obscure (but what would be an obvious 'li'?) to the easily misleading. Frankly, I hope this does not end up in the book. I suppose the hope would be that artistic types would build on this base to something more pleasing, but this will surely not supplant the Latin alphabet for presenting tp (and hardly seems worth the effort at all, except to have something 100% done).
