The bulk of the text story is about other acoustic instruments, but the page has a link to a video story on a radical design for an acoustic guitar. It also shows a science writer for the NYTimes playing his guitar lefty and "upside down" a la Elizabeth Cotton, and sounding as though he would fit in at PT just fine. Worth a look from you luthier types out there. The link should be good for 10-14 days from today (Nov 27).
