I know it's not amazon, since I can't find it on there, but I've always thought that rotating rings would be a great distraction: http://www.geekalerts.com/kinekt-gear-ring/ http://www.amazon.com/Refined-Stainless-Spinner-Unisex-Comfort/dp/B00DJTV6XO/ref=sr_1_fkmr2_2?ie=UTF8&qid=1460066409&sr=8-2-fkmr2&keywords=gear+kinect+ring

I don't know if you're a men or a woman, but there are also more feminine ones, like with rotating gemstones and such: http://www.amazon.com/Sterling-Silver-Turqoise-Bohemian-Spinning/dp/B01BRFBJ7O/ref=sr_1_49?ie=UTF8&qid=1460066665&sr=8-49&keywords=fidget+ring

EDIT: Found Amazon links :)
