Beat Blox is a graduation project by Per Holmquist from Beckmans College of Design in Sweden. The project includes a music machine which allows anyone to create and experiment with music, in a playful and tangible way. The installation includes three turntables, all with built in Arduino, midishield and a total of 15 digital distance sensors. As the user adds a block to the deck, the distance sensor plays a sound. Combining all three turntables produces some quite intricate and fun beats.
