University websites can sometimes be a great store of new ideas. Stanford has a project called The Spatial History Project working toward an intersection of geography and history. The scholars are using the InfoGraphics Lab to integrate GIS and graphic design tools, combined with a contemporary cartographic design aesthetic to produce historical, graphical maps.

These include some geographical and historical maps of Rio de Janiero, such as rent rates and concentrations over time, and income inequality over time (Lorenz curves). There is also an ecological-historical map series of California.

It would be interesting to combine these techniques to a Foucauldian approach to history. The size and location of prisons over time. The number and location of surveillance cameras over time. Number of psychiatric facilities over time, etc.
