Markus Beyr, managing director of Kraftwerk, thought outside the box when developing the multimedia exhibits for the German National Park, Kellerwald Edersee, to ensure they would interest audiences across the board.

"My intention was to create the unusual," said Beyr, who believes most exhibits are too ordinary to excite the visitor, and so spoke with scientists about the best way of engaging audiences. "We transformed things we found in the forest and our daily life into weird, interactive media exhibits, interweaved with a straight message, to cover the demand of the National Park's scientists," he said.

"The main intention is not to give [visitors] hundreds of messages to learn, but to focus on a small number of key messages that are easy to keep."

The landscape is shown from a bird's eye view, and visitors have a joystick they can use to zoom in, fly above the landscape and explore the region. A giant digital wristwatch is a time machine, where visitors can turn the knob to experience different periods and see what happened in the national park at that time.
