Perpetual Calendar Stone

Inspired by Cosmo Wenman, who recently wrote the following on Medium: "It's an inversion of the goal of creating access to a physical space. It's taking a collection and projecting it outward so that people outside the museum can access the designs directly, wherever they happen to be. What I'm advocating is not anticipating particular installations, particular uses, or particular audiences. It's dumping the data online so that the users outside the museum can use it in ways that we could never anticipate or plan for." Source: Objaverse 1.0 / Sketchfab
