Set to be bundled with the Easy Piano instructive game for the Nintendo DS is this Piano/Keyboard controller, which lets you go from punishing ears on a full-size piano, to punishing ears on your handheld.
The game itself seems about as fun as reading theoretical physics when you’re drunk, but the controller seems like it would work nicely with more than a few games on the DS—namely the Korg DS-10 simulator, or future versions of Rock Band-type games—IF it had proper support and wasn’t Europe-only (for now). Even better, someone could always hack it, conjure up some home brew magic, and use it for some live, chiptune wizardry. Mmmmmmmm…chiptuuuune. [Joystiq via Ubergizmo]
