Capture the Pyramid – an interactive projection. The projection changes Karlsruhe Palace into one of the world’s first Megapixel Multiplayer Mapping Games. Spectators, divided into two teams, can take part in the game on their smartphones. The aim is to reach the shiny golden pyramid at the centre of the castle. The game is made more difficult by obstacles, e.g. in the form of virtual holes: if a character touches them, it automatically changes teams and the game continues.
