An anonymous reader writes "The crazy guys over at crowdflow.net are begging you for the location data that your iPhone collected without you being aware of it. All your data will be anonymized, and the whole combined data set of all donations will be shared under an OpenDataCommons license. Those people are data and visualization geeks and create beautiful visualizations like this from the data. They previously did a visualization of data retention caused by the German 'Vorratsdatenspeicherung.' Please consider donating your location data. ...and be fast, too, since the upcoming iOS software update (see Apple press release) will prevent further evaluation of the collected data."
