Entry for the Adafruit 6 Second electronics film festival. This project links a brain sensor via an Arduino to a (laser cut) well filled with single-celled paramecia to achieve cross-species mind control. As the user wills the paramecia to move, the Arduino reads the brain sensor output and sends an electric current through a set of electrodes. The paramecia respond to the electric current and move under the control of the user's mind.

The electrical effect being exploited here is known as 'galvanotaxis' and is a fairly well known (if incompletely understood) effect in paramecia.
