Thanks for the comments, they bring me to the title of this thread - the geometry of tone.
I used to be very involved in audiophile equipment and speaker building, building everything from enormous folded horn speaker cabinets to a pair of 6 foot tall electrostatic panels. (that was an adventure-beautifully transparent audio, punctuated by the sudden arcing of 50,000 volts across the electrostatic plates!)
In speaker building the enemies of transparent sound are box resonances. Great pains are taken to make the speaker box as acoustically inert as possible. In guitar building we are after the exact opposite. We are trying to make the box as acoustically live as we can, across as wide a spectrum as possible. This means trying to excite as much resonance as possible without any obtrusive peaks or "wolf" tones. One of the areas I'm addressing with my design is the actual sound of shape. We are all familiar with the sound of certain shapes, even their names bringing a tonal quality to mind; boxlike. cavernous, hollow, vs open, spacious, airy. In guitars the word dreadnaught instantly implies a booming voice that can be a desirable effect of its boxlike shape. A guitar body encompassing the same air volume as a dreadnaught, but having a curvier shape has a distinctly different voice.
In my guitars I'm using geometry to spread resonances and isolate the tonal qualities of the front and back plates, while still enclosing an efficient, resonant air mass. The front plate is in effect my loudspeaker, the back plate my passive resonator and the rim, my speaker cabinet.
My builds have proven to me the beauty of this design, to the point that this is the way I want to make guitars from now on, exploring all of the possibilities.

Dear Glenn,

this would be a piece of art even without soundboard and back. So I'm really looking forward to the next steps and hope to hear sometime it's voice.

all the best

Thanks! And speaking of art, here's my old artist's brushes. (who doesn't love tool pics?) They're from a lifetime ago when I used to use them for photo-realistic painting. Their use is almost a lost art, in fact the way I used to use them is a lost art--an art lost to computers. These are 3 of my many illustrator's airbrushes and the one on the right was a particularly fearsome beast. It was able to spray hair-thin lines, but also had the propensity to build up drops, right where the turbine-spun needle injected ink into an ultra-thin airstream. It would always wait till a work was almost done and then spit out an inky splatter over everything. I don't think I'll use that one on this guitar! but the others might see service.

Those spray guns did a number. Awesome! And none of those pesky drips. That rosette is gorgeous.

Thanks. Here's an album illustration i did with those airbrushes back in the day. It was fun using tools I haven't touched in probably thirty years!

Yeah, i had a fun period where I painted album covers for The Allman Brothers, Jefferson Starship, Yoko Ono and others (others meaning Kiss, who I always seem to leave off when listing my rock-and-roll, album-cover hall of fame)

I don't blame you.

How does one go from album covers to acoustic guitars?

Actually, I've been building guitars longer than I've been painting. I built my first guitar when I was a teenager, some fifty years ago in the sixties.
Wow. The sixties! It seems "Far out, man" has been replaced by "Way back, man"
