Prague's Center for Architecture and Metropolitan Planning hosted an exhibition representing a strategic plan for Prague's development in the coming decades. We were commisioned to create an attractive visual solution ranging from highly detailed texts in brochures to a game on a giant projection screen. Quite soon it became clear that the most engaging way to tell the story of the plan was to create an interactive game. Sort of like the legendary computer game SimCity. Something, where you can play with original animated illustrations of Prague that respond to your interventions in urban planning. Working with a surface 24 metres wide was a great opportunity to create detailed animations on a large scale. The instructions behind the birth of the new interactive exhibition were brief: “What could Prague look like if you took the planning into your own hands?” The giant projection screen allows to oversee urban development, traffic interventions as well as citizens’ satisfaction with the cultural offerings or efficiency of the links between schools and firms. All this in the form of original interactive animations whose illustration style was inspired by the Isotype approach to infographics and its pioneer Gerd Arntz.
