OSM Ind. Experimental Automata 01: The Skull-Bobber.

I have no recollection of how last night I came to be sat at the dinning table with a roll of wire and a pair of pliers.
The roll of wire looked like a Slinky, but was not a Slinky.

The key to this whole machine is the guide plate across the centre of the housing.

The finished item now looks and moves like this:

Oh, scary.
