I do believe the Iron Builder competition is heating up just a tad. Guy Himber posted a still photo of his brilliant Orrery, to compliment its moving counterpart. It’s just as lovely stopped as it is moving.
An orrery, to quote Guy, is “…a mechanical device that illustrates the relative positions and motions of the planets and moons in the solar system in a heliocentric model. They are typically driven by a clockwork mechanism.”
This completely fits that description.
