PyStopper is an Open Source practice tool designed to assist performers in dealing with the often forgotten third possibility in a performance-induced adrenal response; Freezing.

​

The application will change it's display from green to red pseudo-randomly, and the performer is directed to stop for the duration of the red. They then resume performing at the place that they left off when it turns green again. 

​

The objective with this software was to acclimatize performers to stopping in random places in order to smooth out potential issues caused by freezing or forgetting your place in a performance.
