How does designing for novel experiences with largely untried technologies get its inspiration? Here we report on a project whose goal was to promote learning through novel, playful visions of technologies. To this end, we experimented with a diversity of ambient and pervasive technologies to inspire and drive our design. Working as a large multi-disciplinary group of researchers and designers we developed novel and imaginative experiences for children. To crystallise our ideas we designed, implemented and experimented with a mixed reality adventure game, where children had to hunt an elusive, virtual creature called the Snark, in a large interactive environment. We describe our experiences, reflecting on the process of design inspiration in an area where so much remains unknown.
