There was a proposal for 3D vowel space conventions in a paper in, I think, Journal of Linguistics, by, I think, Roger Lass and possibly someone else, some time around the late 80s early 90s. But the 3rd dimension was for lip rounding. Me I think 2D works pretty well for vowels and tectal approximants, except for laterals and rhotics and rhotacized vowels. One axis for F1 or distance from larynx to constriction, & the other axis for F2 and constriction to labial end of the oral tube. Laterals obviously complicate because of the lateral scrunching of the tongue body, and rhotics complicate because they add a second constriction (or create a secondary resonant cavity). Anyway, the IPA chart is misleading not so much because of its 2-dimensionality but because of its idealization and schematization. What I find more annoying with the IPA is the typographical aspect. Many characters just don't lend themselves to diacritics, because of ascenders and descenders, and the whole thing is rather pragmatic and unsystematic. Better would be some kind of analogue of the musical stave; I seem to recall a phonological notation (gestural phonology?) based on the stave in a paper by ??Colin Ewen and possibly someone else also in Journal of Linguistics from c 1990. Or possibly in Phonology (Yearbook). A compromise would be to have, say, all oral articulations represented by x-height characters, all laryngeal articulations by under-diacritics, and all tweaky diacritics over the main character. That's not a full solution, but it would still make life easier. --And.
