A couple of clips of my modified and updated Hand-cranked Sound Generator (a kinetic sculpture designed to produce a range of sounds by spinning spheres inside a metal bowl/bowls).

Risk Of Spillage
The sculpture’s additional clanking and scraping functions provide a rhythmical accompaniment to the sounds generated by a mix of whirling beads and balls. (Note spillage occuring towards the end of the clip as a bead escapes).
