These beautiful paintings are undergoing restoration at Siegfried's Mechanisches Musikkabinett in Ruedesheim (short clip from the guide's description here).
From the next room (the former chapel) -
There are some nice video clips from the museum here, although the mechnical dolls are a bit creepy - don't click the link if you really don't like the sound of mechanical music! The Bruder Bros. concert organ was the first encounter, a bit overpowering under that vaulted ceiling (click photo for audio link).
Outside the museum. There are bell carillons mounted in the upper window recesses either side of the main entrance (just visible far right), which played on the half hour.
An unusual museum, and worth a visit.
