Interactive designer Tom Jenkins made the audio shaker that traps anything sung, spoken, clapped, whistled or played near it and transforms this sound according to the shaker’s movements, subtle or violent.

LITERAL:
The audio shaker explores our perceptual understanding of sound. Anything sung, spoken, clapped, whistled or played near it is trapped inside, where it takes on an imagined yet tangible physicality. Sounds caught in this void are transformed, given weight and permanance, reacting directly to the shaker’s movements, subtle or violent. Shaken sounds have to settle down before becoming still and silent, behaving more like fluid than transient energy.

The linear timescale of sound is broken, a conversation is split into words and mixed up in the shaker, and can be poured out separately, tipped out in a simultaneous spalsh or added to and shaken up further.
Put simply, it is a tactile container to capture, shake up and pour out sounds. Creating a rich, intuitive experience that is purposefully open to interpretation and imagination.
