I just checked in eigenvalue_ex3. It's an example I made last semester when I was teaching about eigenvalue problems, and I thought it'd make a good libMesh example. We compute eigenvalues of two "isospectral drums": they have different shapes, but their entire spectrum is exactly the same (so, in principle, these two drums would sound the same). This is a well-known result, e.g. http://en.wikipedia.org/wiki/Hearing_the_shape_of_a_drum
Also, it's a good benchmark problem, because the eigenvalues have been tabulated to high precision in the literature (as indicated in the example comments).
