Answer 2

Thanks for posting this question! I had meant to look this up a long time ago... never got around to it :)

The response above has a good link... I like this one better:

The Shell, Dot and Bar symbols being used as a numbering system have always intrigued me!

Of course, their writing system is beautiful... here's a link to an explanation of how it works for those who might be interested:

Another writing system that intrigues me is cuneiform... from another part of the world, of course :)
