Pretty freaky. Extremely sinusoidal — much more than I expected. Then
again, I Only Know What I See On TV™, so I was expecting a Star Trek
shake-the-camera kind of effect. Instead, it was more like sitting on a
wobbly chair than anything else I can imagine; you can sense that there’s a
point of equilibrium, but some external force has been introduced that starts
the system into lissajous motion.
