Yamaha Corp showcased a stick-like device, "Muro Sensor," that can be used to play music by sensing the direction and speed of acceleration.When a user swings the Muro Sensor, the values of the acceleration are wirelessly transmitted to the base unit of the wireless system and, then, to the user's PC. If the PC is connected to a sound generator, preset sounds can be played based on those values.The best part is that it is possible to connect up to 24 units of the Muro Sensor to one base unit at the same time leading to Wii enabled 24 person ensembles.More here:
