This is a description video of the ZatLab App made for Creativity and Innovation Festival 2013, that took place at Lisbon Portugal.
The app allows the triggering of sounds with human body movements. In this case if the hands move faster than a determined velocity, this will trigger sound samples. If the hands are join together this will freeze a sound sample and allow to control it in terms of pitch, reverb and feedback by moving the hands in space. Sudden movements release the "frozen" sound. By crossing the lines on the screen one changes the sound bank. Enjoy.
