Tengu is a cute little plastic brick from Japan that lip-synchs to music and other sounds. Simply plug it into any USB port and it will turn on or off depending if any noise is detected in the embedded microphone in the base. Once activated, one of seven different bright LED faces appears on the Tengu moving and singing to music or voices. Practical, no. Funny and cool, absolutely! Check out the videos below to see Tengu in action.
