POV fan

Liza Stark, 2014

What hidden languages do we use to communicate? How are they transmitted through the objects we use? For instance, Victorian ladies discretely communicated with pursuers through their handfan motions. POV Fan uses embedded LEDs to send written messages using persistence of vision, with angle and speed determining the message. This is a simplified prototype using an ATtiny44 and no accelerometer or gyroscope.
