Exactly. It's done with rapid movements and pauses rather than a
smooth motion. Which for many of us is the best way of inducing
nausea. I suspect that this is why so many people thermal with their
heads rigidly held in position. I find that rotating my head around a
true vertical axis, rather than the local one, works to reduce this -
ie scan across the hosiron, not across the wings.
