Claude Generates Looping Backrooms Video

goodside · x · 2026-07-17

A real-world test of video generation: using the Cowork tool, Claude Fable 5 High generated a Backrooms-style video purely through iterative feedback, without being given any implementation details.

The visuals feature a room where the exit leads to a hallway but constantly loops back to the exact same room, creating a looping "infinite room" effect. The author described the result as "pretty incredible".
