New 3DS attachment for dual Slidepads and potential 3DS hardware redesign

I'd also like to add, if you look at the photo in the OP, it grooves up like a controller, so it's not just a thick bottom that's a straight plane. It looks like it'd fit just fine for my hand.

That's cool, and so is the L2/R2 button inclusions, but with the analog stick to the right of the buttons, it still looks stupid to use.
