I read an article on Silbo Gomero and have been poking around the net since, trying to find anything on the actual language itself and not another copy of that interview that gives practically no useful facts at all. I did find an MP3, but the only words that I can pick out are "hey" and "ok", and they seem to just be single syllables. The language only has 8 letters, and it's not like devising a method for writing them would be that difficult.

Anthropomorphic (body-part) maps are generated by configuring the virtual body of a god or goddess over the area to be mapped. Areas or features under each part of that body receive the name of that part. This produces a "map" on which each toponym automatically indicates its approximate location. Example of these maps include the map of Napi (creator of the Blackfoot Indians) in Alberta, Canada; the map of Hermes in Asia minor; and the map of Aphrodite in north Africa.

Attributes of Body-part Maps
Here are some attributes of these maps that may be of general application:

1. The map tends to cover an area of political or economic influence. Larger maps are associated with larger, more powerful language communities. Larger body parts are associated with larger areas in a map; smaller body parts match smaller areas.
2. Areas of male maps (gods) are later called Fatherlands. Areas of female maps (goddesses) become Motherlands.

One unusual alphabet reform is Alphabet 26, which does away with the two-case system of uppercase and lowercase. Uppercase letters in Alphabet 26 are just larger versions of the regular forms:
