Sphere rotating around two perpendicular axes.

A kinetic scupture. Input: blue shaft. Large gear to which is fixed the sphere has revolute joint with the blue shaft. See the similar joint in Drawing a spherical helix : https://youtu.be/bx6Pn9XReg8 The sphere is driven via planetary bevel gear drive and spur gear one so it rotates around vertical and horizontal axes at the same time. It is possible to hide the rim gear by attaching two flexible bands to the sphere groove walls.
