This program provides a visualization of the waves that ripple across the
surface of the drum after it has been struck.
The user can strike the drum to visualize the waves that result.
The strike can be adjusted by modifying the amplitude (hitting the drum
harder or softer) and by modifying the radius of the strike.
The speed of the waves on the drumhead and the damping of the drumhead
can also be adjusted.
A small resolution demo video is available: here
