Not since industrial noisemakers like Einsturzende Neubauten first miked a shopping cart… This is a decidedly more 21st version. The makers, Hogan Birney, Sean Kinberger, and David Plakon explain the design:
Touch and pressure are used to control the live manipulation of sound and image. The cart is equipped with a video projector, computer and battery making it portable and self contained. Using a microprocessor (Arduino) and custom software (max/msp/jitter) to sense the users touch and translate the pressure of the users touch, a real-time response is created both visually and sonically. The cart is used by MPG performers and the audience is also encouraged to play the cart as well.
