This looks like it might be something out of Stanley Kubrick’s 2001: A Space Odyssey but it’s actually the interior of the Capella Tower in downtown Minneapolis.
The Capella Tower is known for it’s crown and is the disputed tallest skyscraper in Minneapolis. The IDS tower is slightly taller if you count the window washing shed located on top of the building. The Wells Fargo Center is also about the same height but slightly shorter.
Besides the 2001 reference it looks to me like some machine making Saturn’s rings or perhaps the crown for the top of the building.
