velo-city

Velo-city is an interactive data visualizatoin that allows participants to explore the feeling of riding a bicycle from the city of Barcelona to the Monestir de Monserrat.  By moving the dial along the elevation profile of the route, the participant can feel the change in velocity of the bicycle.  A blade less fan blows air through the center of the dial proportional to the velocity of the bicycle at that location along the route.
