The artistic orb that listens to you singing

A hand-held orb that vibrates when people sing to it has formed part of a Vocal Vibrations exhibition in Boston, Massachusetts.

The participant wears a microphone and sings or makes noises to the device. Those sounds are then analysed in real time by computers and cause the orb to respond.

In an online exclusive, BBC Click's LJ Rich finds out more.
