Somewhat disturbingly, in a thread about sandwiches,
gundy has reminded me of the following:
It has been probably 20 years since I saw it (this particular thing, not the museum itself...although even that was probably almost 10 years ago now), but as I recall:
The MSI in Chicago has 4(?) grand stairwells in 4 corners of the original building. Each stairwell had some feature you could look at as you were going up and down. One had a Foucault Pendulum hanging from the skylight 4 or 5 stories up, one had a whole series of large scale gears and mechanical linkages that you could manipulate to see how they interacted, one had....something or other, and one had ~1/2" cross sections of preserved human body in plexiglass, stuck out at right angles to the stairwell wall so they were kind of hard to avoid. Head to toe sections, some horizontal sections (I remember bits of arm and leg in matched pairs) and a whole lot of detail around the head: eyes, brain, tongue etc.
I remember the first time I saw it I didn't understand what I was looking at, and was nonplussed for a few seconds until it clicked into place, and then my brain went into full WOOP WOOP WOOP WOOP mode...except there was no clear place to run. I also clearly recall later on, seeing the little nub of the earlobe and bits of hair around the back of the head on a full blown cross section of the skull, with the nostril holes on the other side.
Wonder what ever happened to the display?
