Below are equations graphed using a new type of graphing called "fuzzy graphing" or "non-binary graphing".
You can click on any of them to open them in FuzzyGraph (the world's first Fuzzy/Non-Binary Graphing App).

Fuzzy Graphs
Digital Cymatics Fuzzy Graphs

Each of these digital cymatics pieces is a single equation. They are each essentially variations of the "Wavicle" equation (below). The "Wavicle" equation is a 2-dimensional sinc function. The waves interact to create wave interference patterns.

Fractal Fuzzy Graphs

The following are fractals visualized in the FuzzyGraph App (though they are not technically "fuzzy graphs" in a strict mathematical sense).
