Bob LeDoux sent us a link to a really amazing site about the Hellschreiber system. The site is filled with great videos, pictures, and animations like the one above. Lots of radio history too. Check it out:

This is all the work of F. Dorenberg, N4SPP. Thanks OM!
Bob writes: I'm working on a microcontroller based reader for
this mode. For old fossils, like us, this mode looks perfect. It can
be sent using simple CW equipment and it appears to be a great
replacement for those who are tiring of Morse code.
Its perfect for Knack victims. We can even build mechanical printers. Thanks Bob!
