3D printed record

Cory Doctorow at Boing Boing has posted a video of a record -- it doesn't look like it's actually made of vinyl, but still -- that was printed with a 3D printer, and actually plays.  (Kind of badly.  I mean, I'm really enjoying watching and listening to it, but that's more because I'm amazed at the technology than that it's a particularly faithful replication of the sound.)

I'm waiting for the way when taking a snapshot of a vinyl disc can be the first step toward deriving its audio content, converting that back to a shapefile, and printing out a high-fidelity duplicate.
