In this chapter, the authors discuss some of the things that we as researchers learned from their development. They discuss the two playworlds of the research projects named the Baba Yaga Playworld and the US Narnia Playworld. The authors introduce Gunilla Lindqvist's interpretation of the Vygotskian theories in which playworlds are based and then present playworlds within Lindqvist's creative pedagogy of play. In Lindqvist's view, the way that Vygotsky links emotions to thought gives aesthetics a new role in the process of consciousness. Lindqvist's creative pedagogy of play promotes the study of joint adult-child play in which children's ability to produce results in play that are novel to both adults and children is a central feature. Lindqvist reinterprets Vygotsky's theory of play through his Psychology of Art, and through a modified reading of "Imagination and Creativity in Childhood", to focus on Vygotsky's assertion that children's play is a creative cultural manifestation in humans.
