  Using analogs of familiar image methods in electrostatics and optics, we show
how to construct closed form wave packet solutions of the two-dimensional
free-particle Schrodinger equation in geometries restricted by two infinite
wall barriers separated by an angle Theta = pi/N. As an example, we evaluate
probability densities and expectation values for a zero-momentum wave packet
solution initially localized in a pi/3 = 60 degree wedge. We review the
time-development of zero-momentum wave packets placed near a single infinite
wall barrier in an Appendix.
