Charlotte Sartre stood at the threshold of Asylum 15–12–31, a near-forgotten building wedged between two modern glass towers. The asylum’s façade still bore the faded numerals—15–12–31—painted decades earlier, a cryptic relic of an institutional system long since dismantled. Rumor in the city said the place had been repurposed, its wings converted into artists’ studios and experimental workspaces. The rumor was true; within its thick walls a disparate community had taken root, and at its pulsing center was the Blender Studio Full.
The content you are looking for is most likely associated with StudioFOW (or a similar 3D animation group). Around 2015-2016, there were several "ambassador" or "patreon" reward animations released.
The combination of these elements suggests a creative project that brings together art, philosophy, and technology in a unique and innovative way. The mention of Sartre and the concept of an asylum or sanctuary implies that the project may explore themes of existentialism, freedom, and the human condition.
