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).

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. Note that these can take up to ~30 seconds to load. (Pending FuzzyGraph update will dramatically reduce this load time, but in the interim, prepare to wait half a minute.)
