The globe is a solid glass ball with the scene trapped within the glass itself.
Attached to the arbitrarily chosen backside of the sphere is an open double walled semi-sphere reservoir, and is the only section of the globe to contain a working fluid.
From the base of the fluid filled reservoir tiny air bubbles are forced through a diffuser to rise languidly to the surface, but from the face of the globe these miniscule bubbles appear to descend due to the optical inversion properties of objects seen through a transparent solid sphere causing the illusion of descending snow flakes.

Given the inherently symmetrical nature of spheres, we feel obliged to challenge this description.

So that would be the Final Front Sphere, would it not ?

The fluid can't be inside the sphere while still maintaining optical inversion and the illusion of falling snowflakes.
Don't get me started on the Moons' spin again...
or religion, or politics, or philosophy, or education, or...

...if you'd be so kind as to point me back towards that rock I crawled out from under, that'd be good.
