Based in the tradition of the Philosophical Instrument this work, a Conundra Object, is based upon an extraction of Kepler’s solar system model and a musing of what existed beyond his platonic “Celestial Spheres”.  Kepler's chrome sphere is supported by hand machined brass and copper supports with a plumb bob centered on space, flanked by illuminated display spheres under glass, circled by a rotating planetoid form, all mounted to a box base of various hardwoods.
