zike, built a pretty cool oscilloscope music player.

As a collector of antique oscilloscopes and fan of engineer/composer Jeroboam Fenderson, he was inspired to build this stereo player.

Using a Teensy 3.2 and an Audio Shield, the player cycles through stereo .WAV files loaded on a micro SD card.  The left and right channels drive the x and Y axis on the oscilloscope.
