Bowed metal tines, friction mallet and Supercollider

Bowing the metal tines from a disassembled toy piano, it has a coarse, harsh timbre that I, with choice processing and editing, wanted to turn into a layer of atmospheric winds for a personal project, but I got heavily sidetracked when I rubbed a friction mallet across the metal folding table which sounded remarkably like a seasick trombone.
A few layers processed with a Supercollider granular + pitch dispersions patch and suddenly I need to go listen to some Giacinto Scelsi.
