From reading the description, i think this might actually be more of a indoor drop tower than a roller ball:
Vertical Dark Ride for ???Conny-Land???
The amusement park ???Conny-Land???, based in Eastern Switzerland, is adding a new attraction for its visitors. The contract for this project, which is planned for 2020, was signed at the European Attraction Show EAS Amsterdam by Roby Gasser from Conny-Land and Willy Walser, RES. A vertical dark ride will allow a unique story-telling experience. This part of the project will be developed by Nick Farmer from Farmer Attractions Development. The ride fits into the concept of Conny-Land, where the park visit shall be fun even in rainy weather. Ride Engineers Switzerland have already built other vertical rides around the globe, which fulfil to the market demand of interactivity and multi-media.
