Geneva base designer Khalil Klouche designed the 'Knock Knock' a playful calculator for small children. When kids knock out a mathematical calculation on the wood surface, it will knock back with the answer. It was designed for the exhibition “Touch!” at MUDAC (Museum of design and contemporary art) in Lausanne in 2012. It was also featured at Lift conference in 2013 and on Nouvo on RTS (Swiss TV). Knock Knock uses original wooden box, Arduino board, contact microphones and solenoids. Check out the video for more info.
