WOW, what a gorgeous top!
As I (may?) have mentioned before, my father and I bonded over the fascinating but challenging magnetic levitation tops when I was a child. The Zephyr may be less of a process to get started, but it also has that "something extra" beyond just being a top. The air-assist mechanic makes this top a fidget-toy; instead of launch then hands-off of most tops, I would constantly be tempted to breathe a little life into it like a top-god. Call me Aslan! Rawr!
Aesthetically, I find it very pleasing and unique. The repeated patterns of the blade symmetry continuously twisting through the body and the lateral ridges on the surface, both please the left-brain and probably anyone who enjoys puzzles, mathematics, or physics. I don't think the ridges/ripples add to the aerodynamics of the top's spin time, but maybe they make the air-assist work better? In any case, they add a texture and sparkling luster to the eye-catching look of the top standing still.
I even find the digital video mesmerizing. As the top's spinning frequency decreases, it phases in and out of sync with the camera's framerate, causing the stripes to morph thinner or thicker and create the illusion that the top is spinning much much slower than it really is. I would love to film the Zephyr with my iPhone's "slo-mo" high framerate modes.
I would love to have one of these if I had a desk job, and I think I could even afford one in that case. Besides being a fidget toy, I think it would be funny if a Boss-guy made it a rule to finish proposals and meetings before the top stops, and rewarding interesting proposals with a breath time-boost. It also would make a great gift to mathematicians, physicists, or even teachers.
