Dotspotting is easy:

Dotspotting is the first project Stamen is releasing as part of Citytracking, a project funded by the Knight News Challenge. We're making tools to help people gather data about cities and make that data more legible. The code for Dotspotting is available for download on Github, and licensed for use under the GNU General Public License.
