… To create custom iPhone cases, Shapeways has teamed with SoundCloud, a software maker that specializes in letting people create and share sound recordings. In this case, you can use a SoundCloud app to record some audio and then create a waveform—basically a picture—of that audio clip. Then you hop onto the Vibemarketplace on Shapeways’s website and select your audio recording. The company will print out an iPhone case that captures the unique hills and valleys of the waveform and mail it to you for $25. (Or $19.95 until March 18.) …

If iPhone cases aren’t your thing, Shapeways has all kinds of other oddities on offer, including a bird’s nestegg cup, bespoke cufflinks, and even a bikini.
