The new Laplacian node [www.sidefx.com] can be used to make a geometry equalizer.

Like with sound, you can exaggerate or reduce certain frequencies (eigenvectors) of the geometry. This can be used to reduce or increase detail in certain areas, for a variety of distortion effects.

Thanks to @WhiteDo27114277 for his Eigenspace Projection example [drive.google.com]! I remade it in OpenCL for better performance.
