This java applet is a simulation of waves in a circular membrane (like
a drum head), showing
its various vibrational modes. To get started, double-click on one
of the grid squares to select a mode (the fundamental mode is in the
upper left). You can select any mode, or you can click once on multiple
squares to combine modes.
