Photographers often attach descriptions and tags when posting their photos on Flickr. The data mining of these tags allows us to infer the kinds of activities that these photos capture. Spaces of activity reveals the regions and cities that host memorable parties in Spain over the course of a year. It also shows the places that attract more quiet experiences through art. The size of the glow on the map corresponds to the density of each type of activity. A greater glow implies a greater density of photographic activity.

This animation of the photos with tags related to "partying" in Summer 2007 shows that Barcelona confines its fun to the old town (Ciutat Vella) known for its high density of tourists, the bohemian distric of Gracia and the Forum area and its music festivals.
