The videos of the AMICA convention showed quite a few of these animated
organs, most of which are old originals with exception of the organ
mentioned by Phil.

Indeed, the web page of Mr. Leible is not easy to find.  Only by using
the German name of one of his organs, "Knoedelfresser", was I able to
locate it:  http://www.magic-mechanical-music.de/
