Since we've been talking about filters lately...
There are several classes of active filters (state variable, gyrator, etc.), but one that's especially interesting is where you start with a passive RC filter, with poles on the real axis, and apply feedback, liberating the poles into the wonderment of the complex plane.

Have fun with it. Tell me what you think. Ask questions. Explore.
