OrigAudio Universal Rock-It 3.0 Portable Vibration Speaker
What it is: The OrigAudio Universal Rock-It 3.0 Portable Vibration Speaker offers a creative way to turn any object into a speaker.
Why it's awesome: The device's "pod" sticks onto any surface and converts your music to vibrations, which it then amplifies through the attached object. You can even chain multiple Rock-It units together to work with multiple "speakers" for a fuller sound.
