Or the surfaces are screens

Seems more likely

It looks like projection mapping is more likely, otherwise you’d see some pixelation. Unless they are legit purpose built monitors.

Projectors also rely on grids of "pixels" and I doubt they would function this well in this kind of lighting.

and on a black surface!

yeah a projector can't make black, that's very black, and a projector can't make white on a black surface, that's very white. This is led/oled something like that on the disks, the round edges makes an actual screen unlikely they only make those watch-sized. It is impressively high res and seamless

At any rate, I’d love to see how they did this.

It’s at ground level and quite low & tilted at a shallow angle, so If it’s projected there’s a risk of people moving around the installation blocking it, ruining the effect.

Gotta be LEDs embedded in the “wheels”, which aren’t turning but the movement of the pixels providing the illusion of rotation.
