Hooray for the phys-L archive.  I found my original message (below)

I stumbled on a totally neet-o wave simulation applet:

  WAVES ON A 2D GRID
  http://www.falstad.com/oscgrid/

This thing lets you do all sorts of demos with reflectors, lenses,
cavities, and point sources.  WARNING!  It's a huge time-waster, and if
you have to grade papers or something tonight, stay away!

The same author has 3D vibrating membranes, plucked strings, and other
cool stuff:
