Every month we offer desktop wallpapers that are designed to feature a particular typography as well as the calendar month. In August 2010, we featured a calender titled 4sq. This particular design had the Foursquare Nerd Panel badge in the forefront, and the other badges in the background. The design was so well received that we decided to make a non-calendar version.
If you are new to Foursquare and are looking for a list of the available badges, and the keys to unlocking them, make sure to visit our Foursquare Badge List. We also have created a Foursquare Badge Suggestion List, which consists of other badges that we thought would be cool.
