I see that recovery.gov -- the administration's website for tracking stimulus dollars -- has gone live. From the site's welcome note:

Recovery.gov is a website that lets you, the taxpayer, figure out where the money from the American Recovery and Reinvestment Act is going. There are going to be a few different ways to search for information. The money is being distributed by Federal agencies, and soon you'll be able to see where it's going -- to which states, to which congressional districts, even to which Federal contractors. As soon as we are able to, we'll display that information visually in maps, charts, and graphics.

There is an interactive map with state-by-state estimated job effects and a chart on the areas to which funds are allocated.
