Beamz Laser Harp
The cool Beamz - Music Performance System or a music generator which is a unique "W" shaped electronic musical device that plays a series of notes with six integrated laser beams that lets you play with the light. When each of these laser beams are broken with your hands and fingertips, a range of musical sounds fill the air. It can reproduce rich, complex music and you don’t need to have any formal training in music or do not need to have any prior experience in musical industry.
Your hand movements control the tempo of each sequence yet the device automatically eliminates discordant 
chords and sour notes for flawless performances. Keeping your hand in-place plays a beam's entire sequence; when you remove your hand from a beam, that beam's sequence stops. Two buttons on the generator allow you to assign different instruments to beams while you are playing.
