Made from aluminium, bamboo, turntable.
This one's also an attempt to use cinetic movement to produce sound. In this case the sound is of two natures : one is percussive - one nail hits regularly the structure - the other is "grindesque" - two aluminium tubes of different sizes are grinded in a circular movement
(similar to the way the tibetan bowl produces sound although the materials and shapes used are totally different).
The resulting sound is not really interesting, though some kind of sonic patterns appear.
Sounds a bit better when capted and amplified via a piezzo contact microphone
