Flickr user musely gets a gold star today for both effort and execution, for this clever series of shots lining up currency with the D.C. buildings depicted on them. We suspect this is one of those things that seems simple, but in practice is a lot more difficult than it looks to get everything in focus and lined up perfectly. The nice thing about our city? You can tour all those landmarks and plenty more without ever having to take any of that $85 out of your pocket.
