This is cool:
The Sound Advice Project, waveforms as bracelets
Designed as a jumping-off point for parents to discuss drug use with their children, the "Sound Advice Project" converts voice recordings into bracelets with rings representing the waveform of a parent's recorded admonishment. They're $18. It's unknown if there is any sort of vetting process for each recording, but I can testify that "Drugs can be fun and informative. And used responsibly can be part of any healthy person's cognitive life" will just fit into the Flash applet's six-second recording space.
