Lickestra uses cones with embedded capacitive sensors. The ice cream sits within the cones and, when licked, causes the sensors to send an electronic signal to an attached Arduino board. The Arduino, in turn, feeds a computer on which a library of melody loops and beats is stored, and that controls the subsequent audio output.
“We worked closely with Arone Dyer, who crafted a four-part composition that included sounds reminiscent of winter icicles and slippery surfaces,” says Baltz. “Each Lickestra performer was assigned to one sound and could play them as short blips of sound or longer phrases merely by licking the ice cream in different ways.”
