Doe asked how the wind-driven octopus whirligig works, so I’m posting a picture of a work in progress along with a video. This one is a crank-driven tabletop automaton, but the mechanics are the same – a rotating cam progressively displaces extensions of the tentacles below the top of the sea chest.
I’m upping the ante on this one by adding a reciprocating sailor’s hat. Making the cam a wedge, rather than a flat disk, adds vertical movement. As with the outdoor version, the head’s a fence post finial.
My “Menacing Octopus” will look something like this when it’s done. https://vimeo.com/54564005
For now, it’s a bunch of parts in a box. :)
