The turning of all or part of an organism in a particular direction in response to an external stimulus: micro gestures, little temporal shifts; to influence the direction of movement, even slightly.

Tropism is a sound installation activated and modified by the sounds of the space it takes place in. The incoming signal is looped and processed and then used to condition aleatoric fluctuations of the control parameters.

Feel free to make sound. It could stay here for a while.
