The iPhone/Android app Skryté příbehy (Hidden tales) allows you to go back in time and give historical figures a hand. Adventures all over the country include helping Einstein complete his Theory of Relativity or Count Silva-Tarouca creating Průhonice park. Download the app to find a path near you, listen to the tales, and answer questions. At the end of each path, you can take a selfie with the figure you’ve helped. For now, the game is in Czech only, but the app's creators are slowly putting together an English version (volunteer translators are encouraged to get in touch).
