What are these treatments?

Can someone identify the treatments on casters on the right side? Pic from Pure Audio Projects gallery.

I'm guessing that they may be sound diffusers, or possibly absorbers. They are there to prevent reflections from the glass window.

I can identify them as expensive

If that's what they are, I'd try to come up with something home brewed to do the same thing for a fraction of the cost. As it is, that's not a concern for me with my current setup. No need for 'em.

The prices there are high, especially considering the questionable designs.

They look like absorbers made of Basotect mounted on a clothes rail on wheels. I forgot, which manufacturer made this dome shape.

It could also be an Auralex Hemisphere diffusor for a couple of 100 bucks.

A cheap solution to have a movable absorber/diffusor in front of windows.

I personally would prefer to put a glass 2D qrd diffusor there, if I had the money and a window front.
