Can't get rid of the voices inside of your head? Well, why not make them louder (and look like a mental patient in the process). Created by Kate Hartman, the Muttering Hat is a goofy-looking hat made up of hacked MP3 players, headphones, and microphones. One form of the hat lets you listen to pre-recorded mumblings as you go about your day-to-day tasks. (Cause you know, listening to music is so boring). The other version, puts your inner thoughts on speakerphone, so as you mumble to yourself, anyone near you can strap off one of the hat's giant ear balls and listen in on what you're saying. In other words, you'll never be able to silently judge someone again. And that in itself is reason enough to pass on this hat.
