Standing wave particle system
I have made a framework for particle systems, and this is first applet to use it. This applet simulates
a particle system where the particles are affected by gravity and the bottom of the container vibrates with
a standing wave. The standing wave will affect the particles when they bounce, and the wave
will become visible through the particles. At the nodes of the standing wave there will be very little
activity and at the anti-nodes of the wave the particles will bounce the highest.
