Work in Progress: Orientation Triggered Audio Object

I'm working on a set of objects that can trigger various samples based on orientation.  I plan on making three+ of the these objects that tether wirelessly to a single amplifier and audio source. I'm not sure what the final enclosure of the devices will be but I have considered the "Junk Orchestra" idea (image below). The choice of samples/audio is also under careful consideration.

Technical: This project uses a Teensy controller and audio adaptor board.  Orientation is measured with Adafruit's 3-axis accelerometer.
