Create a Heat Map of Your Foursquare Checkins

Are you using Foursquare to check in at different places? Then you can use WhereDoYouGo.net to illustrate where you check in most frequently. By letting the site fetch your Foursquare history it plots out a heatmap of your favorite places, like mine below from Stockholm city.

If you are going all in on transparency, you can also create a map that periodically updates itself.
