Eigendrum
Draw any shape and hear what it would sound like as a drum
Draw any closed shape and Eigendrum solves the real physics: the Laplacian eigenvalue problem for a drumhead clamped at that exact outline, using finite elements, then synthesizes the actual frequencies. No sampled sounds, no faked overtones. Draw a circle and the overtones are ratios of Bessel zeros, because that's what a circle actually does. Includes the Gordon-Webb-Wolpert isospectral pair: two different shapes proven to sound identical. No account, no backend, runs from a single HTML file.

Who hunted Eigendrum?
Eigendrum was hunted by Basel Ashraf. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it.
