If so, do they seem friendly?
(Or if not, does the question simply reveal that your correspondent has an alien hand fetish, since he also saw alien hands in an Araucaria muelleri a few posts back?)
Does it help to get closer?
Or would you rather not?
What if we view them from the side? Does that make them more or less hand-like?
What about different colors? How do they change the impression?
(And are these different kinds of flowers, or just a younger and older version of the flower above?)
Is it inevitable, whenever we walk into an alien landscape ...
... that we want something to address us? Welcome us? Reach out a little? Even wave, maybe?
