You can code up any numerical integrator or differentiator with
fexpr~.  That's a straightforward textbook problem that you can use to
make a good demo.

Differential equations are the jumping off point for *everything* to
do with oscillators, filters, resonances, up to Fourier analysis.

Like Andy mentioned--you can't simply code up the
differentiators/integrators into blocks and then string them together
to use feedback.  Any differential equation simulation with feedback
needs to take place in a single object.
