Abstract: An anonymous leaderboard for a monitored computing environments is provided. In response to an entity registering with the monitored computing environment (MCE), an encrypted identity and a dynamic non-fungible token (NFT) are generated for the registered entity, where the dynamic NFT has an associated blockchain technology data structure. The blockchain technology data structure is associated with the encrypted identity. A progress element notification is received from the MCE in response to the entity satisfying criteria for a predefined progress element associated with the MCE. In response, a static NFT, corresponding to the predefined progress element, is generated and stored as a block in the blockchain technology data structure. An entry in an anonymous leaderboard output is generated based on the blockchain technology data structure, where the entry identifies the entity by the encrypted identity.

Abstract: A metronome that marks musical time by displaying a clock face having a measure of music depicted about the periphery includes a rotating indicator that sweeps about the clock face to indicate the rhythm. In one aspect, a computer program generates a screen display having a clock face and a clock hand mounted in the center to rotate continuously in typical clock fashion. Using drag-and-drop techniques, notes and other rhythm symbols are placed on the clock face. As the clock hand rotates past each of the indicia, an audible sound is generated to denote that particular aspect of the rhythm in real time. In addition, a display of one or more regular polygons may be presented to indicate counting in a number equal to the number of sides of the polygon. Polygons may be overlaid to display and sound polymetric rhythms, each vertex corresponding to a counted beat.
