Nice use of the Yamaha MIDI breath controller to make the breath car do three point turns and other fancy maneuvers using your breath.
Irvine Brown has then had the breathing directions of these maneuvers translated into musical notation. (dynamics, tempo, duration of notes, phrasing, breath marks - but no key or pitch). Even a movement of a Hummel trumpet concerto has also been transcribed as a track layout.

This is the cutest video - it shows the first time the magic flute was played by Glenn, a young boy with limited arm movement. The breath controller changes pitch as it is tilted, quite intuitively it would seem, as Glenn lifts his head the pitch increases.
This simple microphone, used as a breath controller, modifies the volume of the keyboard with real sensitivity. Quite Kenny G-esque actually. May the force be with him!
The "Kegel Controller" is my new favourite use of Max/msp+jitter software! It is an interactive art performance using biofeedback from pelvic muscles to manipulate sound and video. Information is collected from the perineometer connected to the performer's perineum. The perineometer output is used to produce sounds and manipulate video on a small LCD display.
The best thing about this work is that it is performed without explanatory documentation, prompting interested audience members to ask the performer how the output is controlled ; .)
Last night I met a great bunch of women at the first gathering of the UTS Community of Scholars for 2010. The group gets together monthly to present where they are up to in their doctoral research projects.
Natalya Godbold’s project about sense making in online discussion forums for those affected by renal failure was really fascinating particularly as it is introducing an innovative methodology to the area of health communication.
Amy Chen’s Visual Melodies is a DCA project which produces an interactive art installation in hospitals to help relieve the stress of patients. I was super eager to learn about how the interactivity is enabled - phidget sensors and active script Flash programming make the ferns grow in the forest scene. Amy has had to hand code the active script herself - she reckons she’s the first to use it with motion sensors in this way. She gave up on using Max/msp+jitter because the colours lost saturation when she brought her video files across.
