Super-creepy, heeby-jeeby, WORST clown ever seen!

What makes these hideously fascinating figures even more fascinating is that you just keep finding them. One YouTube video leads to twenty more. These were marvels of high technology during the Victorian-Edwardian era and were driven by a hand-cranked clockwork mechanism. I tried to find a quite long video shot by a tourist which featured a fascinating museum in Switzerland, mostly a collection of self-playing musical instruments. Can't find it now, but maybe it lingers somewhere in a backwash of YouTube-opia.

I suppose people must collect these at great price, or else they appear only in museums and are seldom - what, played? Cranked? What ARE these things, anyway, and why do I have nightmares about them? The sounds they make are the worst, the creakings and bangings and muffled thuds. 

I mean, clowns are bad enough, aren't they, but half a clown made out of wires, rolling some sort of ball and sticking his tongue out at us, is the stuff of Tim Burton movies.
