Having $100 in your pocket would be so much cooler if it was designed by Martin Joubert. He went all out and created a number of different designs for the 100 USD banknotes, ranging from silly to witty. We especially liked the one with “That’s right.

All in all, even the currency that we have today is nothing but paper, even though it looks official and strict. There is nothing backing it up except for our noble military that ensures that Gulf States sell their oil using only the “green” kind of currency. (Photo by Martin Joubert)
