I just found Akopito’s Sulat Bisaya pages. “Sulat Bisaya” translates to “Visayan writing.”
There’s great art and sulat bisaya imagery but what intrigues me the most is Akopito’s theories on the origin of the Bisaya characters & the story behind the ‘Ka’ character. Very interesting. Here is a click glimpse of the interpretations and you can click through to their site with the link the bottom.
