Re: helicopter hieroglyph
The glyph systems are totally different-only thing remotely similar are the Olmec heads. And the similarity is with sub-Saharan Africa. But it is there.
Khipus-totally unique, another system of communication not via writing. I do not think there is anything similar in another culture, but then, it is an artifact that would disappear easily. (being made out of natural materials)
