The evolution of geocaching density
This is so cool! It illustrates the development of geoaching in Germany throughout the last decade. Each light dot is a new cache and the final density is unbelievable...Groundspeak currently displays 135.481 caches in Germany. Considering the country's small surface (357,022 sq km, slightly smaller than Montana in the U.S.), this is a paradise for intensive geocachers!
I also think the script used to create the video might have great applications on academic presentations and teaching... it would be nice to illustrate, for example, the increase in the number of competitors in a new market, participants in a community, or consumers in a given segment without recurring to the old column graphs. What do you think?
