It is indeed possible!

Have you ever seen the script used to write Cree and Inuit? It is a
syllabary where the shape of each letter indicates the consonant, while the
*rotation* of letters indicates the vowel:

I have read somewhere that the success of this script among the aboriginal
nations of Canada and northern USA depended exactly on its relying on the
*orientation* of letters, because orientation and the cardinal directions
(North, South, East, West) have a very important role in the culture of
these peoples.

But, honestly, I have no idea whether this idea has some rational ground, or
is just one more myth about human cultures.

I also don't know which basis has of the opposite view (that rotations and
reflections are bad for a writing system); I guess that it comes from some
ergonomic evaluation of human visual capabilities.
