Cursed circuits: a capacitance multiplier

According to the Adafruit Blog, a capacitance multiplier circuit challenges electronics intuition. The design uses an op-amp configured as a voltage follower—a common building block—but combines it in ways that create an apparent multiplication of capacitance. It's the sort of circuit that resists immediate understanding, since it doesn't map neatly onto familiar electronics patterns.
