This cute machine packaged in a CD case is One Bit Music.
It is a project by a composer and artist, Tristan Perich. One Bit Music's little heart is a chip that stores 11 songs, in this case his own 1-bit minimal electro music generated by a simple program.
The cool thing is that it is not only a medium, there is a headphone socket and forward/back buttons to toggle between songs, and they're meant to be sold at CD stores, lurking behind regular CDs.
I've listen to the music on the website, and they were surprisingly good. Like its appearance the music is analogue, but with attitude! it keeps on changing, like tide...
