In a tangentially related topic, here's an interesting animation of location tracking of a German politician based on his phone records: http://www.zeit.de/datenschutz/malte-spitz-data-retention http://www.zeit.de/datenschutz/malte-spitz-data-retention Malte Spitz sued to have his telephone provider hand over six months of his phone data. He gave it to Zeit Online who used it to create this record of where he had been. It's probably not too surprising to many people any more, but I still find it amazing when I watch it. And it might be interesting to people who don't realize how detailed the information is. I also think the visualisation is nice.
