Craftster.org, the place where "crafty hipsters share clever ideas" lives up to that promise. User "frogz" has made this one off NES-themed messenger bag, saying, "The general reaction to the bag was to try to press the buttons."

If you've now decided you can't live without your own, you could always get a custom design from R.E.Load Baggage, though it'll cost ya. Awesome bag frogz!
