Census Data Explorer

Erek Dyskant submitted his Census Data Explorer project as part of the Sunlight Labs "Apps for America" challenge.  While only a few layers (poverty and race) are available so far, this seems to be a relatively fast browser for visualizing census data at the tract or neighborhood level.  It appears to be using OpenLayers and Google Maps, and of course the data comes from the Census Bureau.  Good luck, Erek!
