Make puppets together from wooden spoons, and then record their spontaneous puppet shows on Storykiosk.
Storykiosk encourages people to record and share stories through their own voice.
Storykiosk has been developed based on the research that indicates that the best sign of learning in museum exhibits is when visitors communicate about their experience. Over the years, the developers of Storykiosk have been adding new layers for ways people can share their experience, including a cloud-based content management system, workflows for social media sharing, and imaginative media formats for display such as the Story Waterfall, which projects recent storytellers’ images onto a video waterfall.
