One day I'll muster up the motivation to bring my setup to Roaring Camp to scan those Shay geared locomotives but those moving parts will indeed appear weird and distorted.

I'm mostly curious if those distortions capture a sense of movement or motion in the pistons, with their regular sinusoidal beats. And no idea how steam clouds would come out. Our minds also visualize the moving parts differently to how a regular camera captures them or the eye sees them.
