Federal Spending mashup Map

Today I found a cool mashup site called Federal Contracts by State that combines government data (FedSpending.org) with a US map (Google Map API) to give a visual idea of how our government spends its money. This mashup is really awesome because it breaks down each state into subcategories like top products and services, top contracting agencies, top parenting companies, etc. I find this especially useful if I were doing research on what companies I think I government offers more "aid" to than others. Also, it breaks down these numbers by year so you can get an idea of the growth or deterioration of federal spending in certain areas.
