I am always interested in new interfaces for performing music, especially if they are functional, expressive and the user doesn’t look like a total dork using the device. That last factor may seem unimportant, but I have to say I have seen many alternative interfaces that make the performer look completely absurd. There is something to be said about the form factor and ergonomics of, say, a guitar, which is probably why I feel like this guy nails it in every respect:
It is original, functional, expressive, looks comfortable and sounds amazing.
