The ones I have seen at shops, or more specifically adverts for cleaning
shops, are ones that push water onto the carpet and then pull it back
off again. Used with water, they are called carpet shampooers around
here. The vac I used worked like a normal vacuum, but instead of a bag
or bin it just funneled the air into a container of water. Absolutely
disgusting to watch water turn from clear to filled with the stuff one
house could hold on the floor in a week. Worked better than HEPA
filters, though.

Oh, I would and have. Just not pop-art.

Also a good reason. However, I can not see many directions to take the
fan concept. Higher speeds, maybe, or floor stands.

Now, if they made a humidifier version, and added blue LEDs inside the
turbine to make the mist glow, then I might get one.

Sounds like a DIY project.

I was thinking about trying it with a polystyrene ball.  Point the fan 
upwards.  Throw the ball up into the ring.  The air flow carries it 
through.  Then would it be trapped in the stream above the ring by the 
Bernoulli effect ?

Yes. Dyson made a video where they routed balloons thru many dozen of these 
things in a big loop.

I imagine it would, much like a toy I had when I was a kid.

I suppose the definition of 'cool' would be the trick. To me, hand made
jewelery is cool, even if it is just driveway gravel wrapped in plastic
electrical wire. Cheap old cameras are cool, more so if I can make them
work again. Bow-ties are cool. Non-functional? The doll that happened to
match my desk so well that she has sat on it for years without being
noticed often. Some old networking hubs that will look nice in the 19U
racks that serve as storage cabinets. An old brick car phone.

All cheap, but all purchased because of that 'oh, cool, I don't need
that but I want it' factor.

If you were scoping to see what was worth stealing, not a whole lot. ;-)

Right, for the cheap knock offs. That way, when the liquid fries one of
the motors, I am only out a few dollars.

Good job I did not reply in High Dudgeon. ;-)

Drat.  Not worth the airfare.

A tank of propane may have some possibilities with one of these although 
they probably are not powerful enough.

Once upon a time I worked as a sysprog for a bank.  There was an 
incident when water condensation built up in the air conditioning units 
on Level 3.  The outlet pipe had become blocked and water spilled over 
the collection pan, found a crack in the slab, trickled into a light 
fitting and collected until it broke the fitting and dumped out. 
Estimated to be about 10 litres of water.

Then the real drama began.  Level 2 was the main computer room.  The 
light fitting was the one sitting above the disk system housing amongst 
other things the volumes for the mainframe running the production online 
system.  Water + Electronics = Failure.

Much mayhem ensued.

The link is that one of the IBM engineers had the idea to get some 
industrial gas heaters in to help dry things out.  These were large 
blowers with gas burning in the air stream.  Crank up the speed and 
amount of gas and they were quite impressive.  Somewhere less than a 
rocket motor but still a *lot* better than a hand electric hair dryer.

Quite an interesting day.  I had a spare system image on another disk 
unit on the other side of the computer room.  We got the system back up 
in the evening and got through batch in time for the next day.  The 
affected unit was rebuilt.  It needed some new controller boards but the 
physical drives were fine.  No data lost.

Good blokes those IBM engineers.

Not so good is the idea of putting the air con plant directly above the 
computer room.

In the land of checkered planes and mirrored spheres, how could I not
like op-art?

Should have said pop-art and minimalism. I still wonder how a black
square on a white canvas was influential so long after the invention of
both black ink and white canvas. But that is an off-topic art rant.

Some minimalism is OK (IMO) but I think it can be over done. (Is that an 
oxymoron?)
