I'm still under the impression that the inner circle will move (but could be wrong), but the movement seems like it will just add a visual element that will be mostly visible from ~Mexico to Canada and ~Japan to Italy.
If that’s even close to true, that represents an astonishing lack of understanding of the venue the show is being designed for.
And, it’s not like they had to reinvent the wheel... Various iterations of Illuminations have played successfully ‘in the round’ for over 35 years, using a basic and well understood central scenic element... A sphere.
