'Ellipsoidal glasses' are created by stretching polystyrene spheres to different aspect ratios and then suspending the resulting ellipsoidal particles in water at high packing fraction. By measuring displacement correlations between particles, we extract vibrational properties of the corresponding \"shadow\" ellipsoidal glass with the same geometric configuration and interactions as the 'source' suspension but without damping.
