This is pretty nifty: an artist has devised a device which fits into a CD jewel case and makes minimalist glitch electronica; the device is meant to fit into the standard album-based music distribution infrastructure, and to be purchased in shops; it will be released by a label named Cantaloupe.
The device looks somewhat minimal, and leaves a fair amount of space in the case; I imagine it could be expanded to less-minimal implementations. I imagine it wouldn't be too hard, in theory, to implement a sample-based music player (of the tracker/chip-tune variety) in that form factor, and provide it with enough algorithmic-composition logic to semi-randomly reconstitute/transpose/harmonise beats, basslines, chords and melodies into something resembling music.
