This is a piece which uses a ventriloquist doll as its main controller. The beginning is just for voice and Max. The doll enters approximately around 4:10.
The doll sends data from an accelerometer placed in her head and a multi-touch sensor (by Phidget) placed in the body (it is activated when the mouth opens and closes)
Most of the sound is synthesized in real time in Max (there are also some pre-recorded files).
