I heard about an interesting site today that converts texts into a number of different shorthand systems, including Pitman, Gregg and Deutsche Einheitskurzschrift (German Unified Shorthand).
Here are sample texts in each of these systems made by the converter:
Pitman Shorthand
Gregg Shorthand
Deutsche Einheitskurzschrift
Where’s the link?
Here it is: http://home.tu-clausthal.de/~rzsjs/steno/Gregg.php
Ah! And it has a Sütterlin section as well! Nice.
