I would have thought most Network Interface Cards contained enough
circuitry to flash an LED :-). The problem might be getting access to
it,.as it's likely to be hidden inside large chips...

A reciprocal impedance converter circuit. Basically, you connect an
impedance to one side of a gyratorm, and the other side appears (to the
rest of the circuit) to be 1/<that impedance>. It can make capacitors
look like inductors and vice versa.
You can make one using an op-amp.
