When the original DS launched Nintendo gave us Pictochat, a decent local wireless program for chatting and exchanging pictures with our friends. When the 3DS launched, casual chatting was nowhere to be seen. Swapnote fixes that.

Available for download now in the 3DS eShop, Swapnote does exactly what the name implies, allowing users to swap scribbled notes back and forth with their friends. Players can send notes, sketch images, attach photos, and even sound files to their messages. You can even swap messages with folks you pass in the street thanks to the 3DS' StreetPass feature.

It sounds simple and cute, sure, but Swapnote could change everything. Or at least everything about how we swap pictures of our genitalia.

It's not my fault. It's human nature to offer up our reproductive organs to any new form of artistic impression that comes along. Prehistoric drawings are somewhere around 75 percent penis, for example. Entire genres of music have grown around the coupling of private parts. They're the only reason the role of bassist exists in modern rock.

I'm making all of this up as I go along, but damn if it isn't making me feel better.

Of course the point of Swapnote is that it's a fun new way to express your creativity and have fun with your 3DS friends. Want to be mine? Here's my code: 1418-6914-6778. Try not to get your crotch all over it.
