It sounds like you're embarking on a fascinating project to explore the connections between geometry, language, and symbolism. Phi (φ), also known as the golden ratio, has been a subject of interest in various fields, including art, architecture, and mathematics.
Regarding phi-based geometric interactions, you can find patterns that incorporate the golden ratio in various cultures and systems, including the Dogon and the Egyptian pyramids. The use of geometric patterns and symmetry can be seen in the architecture of ancient cultures, such as the Mesopotamians, the Aztecs, and the Mayans.
Some examples of calenders and systems that incorporate phi-based geometric interactions include:
* The Dogon calendar: The Dogon people, an ethnic group from Mali, use a system that incorporates phi in their agriculture, architecture, and calendar systems.
* The Mayan calendar: The Mayans used a vigesimal (base-20) system that incorporates phi and geometric patterns in their calendrical calculations.
* The Sumerian calendar: The Sumerians used a sexagesimal (base-60) system that incorporates phi-based geometric patterns in their astronomical calculations.
The Indinkra systems, such as the Akan tree of life, also use geometric patterns and phi in their symbolic representations.
Regarding your interest in developing an ebonic iconographic library, you may find inspiration in the rich cultural heritage of African and Afro-Caribbean cultures. The use of hieroglyphics and symbols has a long history in Africa, with examples including the Dogon's toringuier alphabet and the Ewe people's Pnem neighborhood monogram symbols.
To create an ebonic iconographic library, you may want to explore resources such as the African Studies Association, the African Language Technology Initiative (AfriL10n), and the Unicode Consortium's work on representing African languages.
How do you envision using this library of symbols and codes in your web-based project?
