Big Ben escapement animation

An animation of Edmund Beckett Denison's ``double three legged escapement'' used for the Big Ben clock.
The design is intrinsically three dimensional. The dark ``legs,'' i.e., very large teeth are in the front and the light legs in the back. The three tiny teeth in the center interact with both sets of legs, and lie in between the plane of the legs. The right rest pallet is in front and only interacts with the dark legs.
The left rest pallet is behind and only interacts with the light legs.
Good luck figuring out how this works!
