I have a small idea how much work just one arc is - let alone a whole movement. Add the black polish you see on some surfaces and this is exquisite.
It takes talent, time and hard work to create something like this. Not only do you have to know how-to but you also need equal amounts of perspiration and inspiration to achieve this.
(I am not engaging in the eternal discussion about frosted surfaces versus Geneva stripes - by now at least some you should know my opinion on that subject).
