Interesting project.
Here is a Gem version of the basics.
Also I'm trying to make one with [pix_sig2pix~]

The sand still could be tricky... you would maybe have the individual
particles at random locations, initially, and compute a gradient of
the vibrations to determine movements.

The patterns probably depend on the stiffness of the plate/membrane as
well as its shape, and the grain size and density of the sand.
It should depend on stiffness, density and shape. The speed of sound
in a material is sqrt(stiffness/density). The partial differential
equation for waves
Robin - 1st order differential equation (specifies a constant phase
difference between incoming/reflected waves)
for accuracy sake the phase difference is dependent on frequency
(it works like an impedance)

Obviously this will be done in
Amazing idea for a project Carl.
The way I see it you have two routes.
1) Do a full finite element physical model of a circular lamina
and measure the amplitude at many points on the surface. The sand
falls into minima nodes iirc .
2) Cheat. Create the visuals by mapping the known standing

Yeah. Cool!

To me this whole idea seems rather difficult, if not impossible, to
implement. We are talking about interactions happening at the atomic
level of matter here.
It's not really the atomic level that we have to implement. You can
actually treat the material as continuous, and sampled at discrete
