Geekologie has turned us on to something cool. Something that we feel should have existed a long, long time ago.
 

 
That's right, they're NES Cartridge Harmonicas. Finally, there's something classy for when you want to accompany yourself while playing Guitar Hero!
 

 
Apparently you can only buy these beauties on eBay and they're just over twenty bucks, which seems pretty reasonable for such a cool harmonica. But what we'd like to know this: if we took one on stage during some 8 Bit Music Festival, would Pete Seeger get mad and try to plug it in?
