When I was living in Kathmadu 20 years ago (yow!) this summer, I found this awesomely makeshift ferris wheel in a nearby theme park. A teenager would stand in the middle, and walk from one bar to the next, giving passengers a slow, staggered ride.
Much more recently in southern Laos, down on the island Don Khon, I stumbled across a close cousin: the makeshift merry-go-round or carousel. I think there was a generator giving it a little power, but the operator had to push it around for it to keep any momentum. For context, this is an island where rooms cost one dollar a night, there’s electricity for only a few hours a day, and the closest email terminal was an hour away.
Here’s a short video… pretty awesome.
