"Here's a brand new Ototo Musical Kit in the box with the manual. Got a for a gift but it was never used. Despite it being awesome. As the website says:

"Build a piano out of vegetables, make a plant sing or create a keyboard from aluminum foil. Connect anything conductive to Ototo using alligator clips and turn your touch into sound – the world is your musical oyster!"

Comes with:
• Ototo board.
• 12 alligator clips.
• Illustrated musical guide."
