My pre-band, pre-digital-devices fidget spinner may have accomplished something. Held on sides w/thumbs and spun w/other fingers. My parents and grandparents said I would spend hours at it. Isn’t that the purpose of the current electronic version of fidget spinners; to entertain and calm?
Nimble fingers help high-speed clarinet-ing?
Perhaps I should have marketed the concept (anybody remember pet rocks?).
