sound canvas

I once came across these sound canvases in an art supply store. They had the last two pieces and the American firm that makes them no longer exists. For me, as a music lover, an amazing thing to experiment with. I chose Pink Floyd and Dave Brubeck Quartet for these canvases.
You can at least listen to what they actually really play on your mobile. Just scan the Spotify codes.
