The picture you see here is a bracelet modeled after the waveform of someone saying "I believe in you." Made by a group called The Sound Advice Project, it is a way for parents to record a message, which is then custom-made into a piece of jewelry as a gift to a teenage child. The purpose is for the child to always have a visual reminder of the advice.
Though primarily an effort against teen drug abuse (thus the focus on parent-child advice), the geeky-cool nature of this bracelet is undeniable. Check out the official site, where you can record a six-second message and buy your own waveform bracelet for $18.
