I've been using the Moves app for a little while to have a bit of fun with recording where I visit, when, and how I get around. At this stage I don't know exactly what I'll do with the data, but I've just come accross the Hello-O-Scope, a project of Halftone, that takes the Moves data and nicely maps it. Transit, running, and cycling lines show with higher intensity when they're more regularly used.
The image above is taken from my last few weeks of activity - I can't wait to see what this looks like after a few months or even a year.
