Abstract
A spinner anchors to a variety of magnetic and non-magnetic surfaces. The spinner includes a base, a spinner arm rotatably coupled to the base, and an indicator coupled to the spinner arm. The base of the spinner is shaped to receive a coupling member, such as a cylindrical magnet, configured to anchor the spinner to a plurality of surfaces regardless of their orientation and maintain its location relative to the support surface while the spinner arm and indicator rotate.
