Right now, a roll downhill in a giant inflatable ball sounds like just the thing (Flash). A wander through Flickr led to a photo of a Zorb. A what!?! A Zorb! Several, in fact. It turns out that Zorbing has been around for some years now. It started in New Zealand and is catching on in the UK. It's not widely known in the US, and as a US person I've been un-blissfully unaware.
