The sponge is a piece of foam equipped with sensors (accelerometers and force sensing resistors) which can detect when it is squeezed, twisted or shaken. Sensor data is then sent wirelessly (XBee protocol) to a computer. It could probably be used to control any kind of digital process (like video or lighting), but I designed it as a musical interface. I use it in live performances to control sound synthesis and processing.
