Shackle USB stick and card game, a project founded with donations via Kickstarters. Shackle (Anne La Berge on flute and electronics and Robert van Heumen on laptop-instrument) have designed a digital cueing system suggesting sonic choices to play with and against in their improvised performances. On the basis of their system, I developed the Shackle card game, which is a playful, accessible, adaptation of the concept allowing anyone to try it out. The music is released on an USB stick.
