Ordinary folks can engrave a bracelet or ring with a personal message. For a more cryptic approach, The Sound Advice Project will record your voice and transform the waveform into jewelry. I stare at waveforms all day long, and these bracelets look like they're a close representation. But let's avoid a discussion about what their sampling rate and quantization levels are.

The bracelets were conceived for parents to create discrete anti-drug messages for their teens, with a portion of the proceeds going to anti-drug programs. However, there's no reason that has to be its only purpose. Who needs diamonds — what woman wouldn't adore a bracelet that says, "Thanks for putting up with my video game obsession?"
