Now I remember: it had been discussed in this list!

It was a discussion between Doug Ewell and Peter T. Daniels about "What
makes a good script" and the G.B. Shaw's alphabet:

Perhaps Adam was talking about Hangul vowels? There are 8 vowel letters
whose symmetry suggest rotating the same basic shapes.

Two letters are vertical strokes with 1 or 2 dots on one side; the other 6
letter look like the same 2 shapes rotated 3 times by 90 degrees, obtaining
6 more letters.

Notice that I wrote "look like": I don't imply that the inventor(s) of
Hangul actually rotated letters and attributed a meaning to this. Perhaps
they simply used all the possibilities of a few basic strokes, so that the
resulting letters where not too much complicated.
