Vortography / Alvin Langdon Coburn

[David Hedley]

I've been looking at some of the 'vortographs' of Alvin Langdon Coburn, and I'm interested in understanding his technique more. The best description I can find of the 'vortoscope' is;

Coburn invented the Vortoscope late in 1916 by binding together three of Ezra Pound’s shaving mirrors and rigging them below a kind of glass light table. The mirrors acted as a prism splitting the image formed by the lens into segments which Coburn then used to produce his vortographs.

I can't find a picture or a drawing of how the mirrors were arranged, and where the camera lense would sit; does anyone have one they could share?

I find a reference to kaleidoscope related to vortograph (probably the Vorticist literary movement of the time) so maybe kaleidoscope searches might help.

What was the bearded Ezra Pound doing with 3 shaving mirrors? After the war many would have liked to employ his razor to a different purpose, I understand.
