The Cyrillic script[1] and the Armenian alphabet[2] were also devised in similar fashion, and probably many more. It is not unusual for writing systems or alphabets to find widespread usage in this manner.
The Canadian Aboriginal Syllabics is another one. It was developed by a missionary that noticed that when aboriginal where written in latin script the result was often long and awkward.
