"Impedance matching is one of the perpetual confusions for new electronics students, and for good reason: the idea that increasing the impedance of a circuit can lead to more power transmission is frighteningly unintuitive at first glance. Even once you understand this, designing a circuit with impedance matching is a tricky task, and it’s here that [Ralph Gable]’s introduction to impedance matching is helpful."

This video provides mechanical demonstrations of impedance, SWR, and some other related concepts, making them much more intuitive: AT&T Archives: Similarities of Wave Behavior.

Pros: He never uses the term "complex conjugate"

Cons: Ancient, black and white, monotonous droning.
