The design is based on the classic Celtic-style knot symbol for the World Tree from Norse mythology, Yggdrasil.
Inside the leaves you can see a small sphere of blue. If you look reaaally carefully, you could notice that the continents in the blue ball are in the shape of Pangea and not our current distribution.

This is a bottle. But not just any bottle, a special bottle. This bottle has no top or bottom, nor a front or back, nor even an inside or outside. This special bottle is called a klein bottle.
Klein bottles are non-orientable objects, meaning they have no definable sides. The outside flows to the inside and back again, making it impossible to discern between the two.
Of course, this isn't a real klein bottle. It would be physically impossible to create a real klein bottle. Like my mobius strip-based models, this is the closest possible 3-dimensional representation of the object. Still, it's mathematical and theoretical properties are evident and fascinating.
