Remember Tomas Henriques’ Double Slide Controller? The Meta-EWI is a sort of ancestor to that device. Based around an Akai EWI breath controller, the Meta adds four force-sensitive resistors, an accelerometer, joystick and 16 tactile switches. The add-on structure is also removable and can be used as a standalone interface. More pics and a deeper explanation can be found over at the Electrotap blog.
