Okay, so using this page:http://www.hethport.uni-wuerzburg.de/pi ... ltbab.html
I tracked down an old Babylonian font and "on-screen-keyboard". Then I learn than old bab was some sort of syllabary and doesn't have toki pona syllables. The ideograms seem more promising, but a quick look at some ideogram words shows they don't necessarily match up to toki pona's words (maybe they do. this is rapidly exceeding my attention span. In any case, the ideograms are much longer looking than the symbols for phonetic syllables.)
Worst of all, I after I put the clay tablet in my computers DVD slot, it didn't go anywhere. I don't think the tubes in my internet have enough suction power to deliver my cuneiform toki pona message.
