Pyra may be close to the Golden ratio but for me, it's just not that "beautiful" design at all. A brick may fit in the Golden ratio but this doesn't make it a beautiful brick.
maybe with half the thickness but the Pandora/Pyra is actualy not a nice design. It may be functional and good but not "beautiful". Of course these are just opinions and everyone may have adifferent one.
I would have done an different design if I would have had the opportunity but OK, we have to live now with the current pyra appearence.
