iPhone cases tend to be pretty generic, but if you can make a sound, you can have your own completely unique case. That's because Shapeways will turns sounds—any sound—into an iPhone case.
The 3D printing company has teamed up with Soundcloud to turn audio into wearable art. Upload an MP3 to Soundcloud, or pick one from its database, and Shapeways will make a unique case with the waveform from your sounds printed on it.
Shapeways CEO Peter Weijmarshausen helpfully suggested to BusinessWeek that you might turn the sound of your own child's cry into a case. But trust me, as a new parent, that's not something you want to be reminded of. Let's just stick with a song. [Shapeways via BusinessWeek]
