Dont get crazy...it's just a design competition. Reserve the "Obama replaced Washington" anger for a different blog. This is waht we like to call....hypothetical design. SF-UK design firm Dowling Duncan put thier spin on the US note....adding a techni-color look, rearranging how you read the bill and varying the lengths of each bill (" so that when you stack your bills, you can instantly eyeball how much you’ve got"). Fun-ness.
Identify bills would be alot easier. But every other notion about the bill...has been done in other countries. Kinda-sorta.
