Unless you've been living under a rock, money is on the mind of everyone these days. The state of the economy, not only in the U.S., but the whole world is going through quite an upheaval. So, in a weird sort of way, I've turned my attention to the design of money itself.
I found this interesting website that chronicles currency design in different countries of the world over various time periods. What I find interesting is the various design aesthetics, and how design can impact meaning, as well as stability. Our U.S. currency is not fully represented on this website, but can be found at our Department of the Treasury, Bureau of Engraving and Printing.
And if you need to find current exchange rates, check this site out.
