I got one at a concert this summer, was a little too intoxicated to learn it there , tried it a few times at home - but my problem is standing in one place. It definitely takes some concentration to hoop, but it doesn't really occupy my brain. I guess maybe if I were a TV watcher, I could clear enough space to hoop in front of the TV...

(PS - the one I got is just five pieces of PVC pipe with the male/male connectors in between them, covered with a tube of pretty cloths. Looks like it would be very easy to make.)
