djc - thanks, that looks very interesting, I've bookmarked it. I've watched a number of interesting animations recently and when done well they pack an enormous amount of easily-assimilated information into relatively short videos. The educational power of them is impressive.

An aside. The photographs of O Winston Link capturing the final demise of steam in USA deserve a revival. Some of his prints are truly "iconic".
The way in which he used dozens of old fashioned single use magnesium flash bulbs in a single burst is amazing.

Doonhamer - I'd never heard of him but yes, even a quick browse shows them to be well worth browsing again - thanks.

Yes, an enormous amount of information, perhaps too much when animated. I find I want to pause and study rather than watch the fleeting image; but when stilled even HD video is low resolution. Really needs to have interactive control: pan, zoom, disassemble. Still, takes me back to the sort of thing whose details I would pore over 60 years ago.

djc - it takes me back to the cutaway drawings in Eagle comics of the fifties.
