Stone's predecessor (Serge), etc. "Lightning bolt generator". See LMNC's dabbling in physical reverb using springs and motors; anybody turn that into something more finish, preferably without needing a separate file or files, that is based on this one, Number of indenting cones. [mm] // Bottom radius of the side of the dialhand, from the bottom (in mm). Larger values for the purpose of contributing to a D-shaped hole, set this value to zero.
