He seems to be very productive. In addition to teaching, he writes a lot, including several books, and has even contributed essays to NPR.
The Endangered Alphabets project features "Inuktitut, Baybayin, Manchu, Bugis, Bassa Vah, Cherokee, Samaritan, Mandaic, Syriac, Khmer, Pahauh Hmong, Balinese, Tifinagh and Nom, carved and painted into a slab of Vermont curly maple." He says that:
at least a third of the world’s remaining alphabets are endangered–-no longer taught in schools, no longer used for commerce or government, understood only by a few elders, restricted to a few monasteries or used only in ceremonial documents, magic spells, or secret love letterswhich is why he created the book and project that he plans to exhibit in various places.
It sounds like an interesting project, and I'm glad he succeeded in raising the funds to carve and take the show around.
