Visit here to see what these things look like in motion:
http://www.falstad.com/ripple/
Mine will hopefully be fully programmable when it's finished, but this
shows you what can be done.

...and yet here, it takes less than 10% of my dual-core monster machine. ;-)

Where were you in my "physcodellic" youth, Scot?
Groovy Baby :)

o.o
That should have a public health warning accompanying it!
Clever stuff though.

Yes.
Now check out the rest of that entire site. He had a wave tank, some
stuff about 2D resonant modes, a drum head simulator, a plucked string
simulation, FIR and IIR digital filter demonstrations, some stuff about
quantum numbers, a simulation of heat/pressure/volume in an idealised
gas, simulations of magnetic and electric fields and how they interact,
an extremely neat analogue circuit simulator... and that's just what I
remember off the top of my head!

That seems ridiculously slow, even my POV version can do about 3 frames per
second with a 100x100 grid!

Even on a single-core AMD Athlon 1700+ 1.5 GHz CPU?
Actually, my current revision of the program manages in excess of one
frame per second even at 400x400. It's just nowhere near "realtime" speed.

That seems a considerable improvement from before!

I didn't actually measure it accurately before. It just "seemed" to be
taking forever.
