It's not the first time I've seen someone try the idea seen here. What they've done is take a classic thrill ride, and give it some inverted style restraints so your feet dangle free. I've seen this done before with a magic carpet ride in Tivoli Gardens in Copenhagen. They gave it inverted style restraints and added fountains under the ride that turn on and off during the ride program with your feet dangling over them at some points. The result is quite a good family thrill ride.

Here they've put inverted style restraints on an inverting swinging ship style ride. To be honest here I don't think having your feet dangling free makes much  difference. O.K. your feet are loose, and there's a few instances where being able to see down adds to the view, but it's still really just the same ride experience of swinging on a long arm, including doing a full circle when it reaches it's maximum swing. It's an O.K. thrill ride, but it doesn't produce anything that memorable.
